What is an organic chemistry solver?
An organic chemistry solver works out orgo problems and explains each step. QuizeGpt is an organic chemistry AI solver that goes further: it names the reaction type, follows the electrons arrow by arrow, and explains why the product forms. You learn the pattern, not just the answer.
- Type a problem, paste a screenshot, or upload a photo of a structure.
- Get the product with the full mechanism, in plain words.
- Ask a follow-up if an arrow doesn't make sense.
What the organic chemistry problem solver can do
From naming your first alkane to multi-step synthesis, here's what this organic chemistry reaction solver handles, and how it explains each one.
| Organic chemistry topic | What you get |
|---|---|
| IUPAC naming | Finds the longest chain, numbers it, and names each group in order. |
| SN1 and SN2 | Says which one fits and why: the carbon, the nucleophile and the solvent. |
| E1 and E2 | Finds the β-hydrogen, applies Zaitsev's rule, and gives the major alkene. |
| Addition reactions | Markovnikov and anti-Markovnikov, with the carbocation step shown. |
| Stereochemistry | R and S, chiral centers, and inversion or racemization. |
| Aromatic reactions | Electrophilic aromatic substitution and ortho, meta or para directors. |
| Carbonyl chemistry | Aldehydes, ketones, acids and their reactions, step by step. |
| Synthesis | Plans a route from start to product and explains each reagent. |
| Spectroscopy | Matches IR and NMR data to functional groups and structures. |
Organic chemistry solver with steps: worked examples
This is what the orgo solver gives you. Each step names the rule and why it applies.
What is the major product of CH₃CH=CH₂ + HBr?
- H⁺ adds to the end carbon (C1), the one with more H's.
- That leaves a more stable 2° carbocation on C2.
- Br⁻ attacks the carbocation on C2.
Answer: 2-bromopropane
2-Bromobutane reacts with NaOCH₂CH₃ (a strong base) and heat. What is the major product?
- A strong base and heat point to E2: the base pulls off a β-H as Br leaves, in one step.
- There are two β-carbons, so 1-butene or 2-butene could form.
- Zaitsev's rule: the more substituted alkene wins, and trans is more stable than cis.
Answer: trans-2-butene
Name CH₃CH(CH₃)CH₂CH₃.
- Find the longest carbon chain: 4 carbons, so the parent is butane.
- There's one CH₃ branch, a methyl group.
- Number from the end closest to the branch, so it sits on C2.
Answer: 2-methylbutane
What forms when 1-propanol (CH₃CH₂CH₂OH) reacts with PCC?
- 1-Propanol is a 1° alcohol.
- PCC is a mild oxidizer: it turns a 1° alcohol into an aldehyde and stops there.
- A strong oxidizer, like KMnO₄, would keep going to the carboxylic acid.
Answer: Propanal (CH₃CH₂CHO)
Try it without signing in
Pick a sample problem, then drag a box over it to snap it, just like the Chrome extension does on your homework page.
Bromoethane (a 1° halide) reacts with NaOH, a strong nucleophile. Which mechanism is it?
- SN2
- SN1
- E1
- Free radical
Drag a box over the question, just like in the extension. On a phone, tap it. Or press Snap & solve.
- A 1° carbon is easy to reach and forms an unstable carbocation.
- A strong nucleophile can attack right away, in one step.
- One step with backside attack is SN2.
Which carbocation is the most stable?
- Tertiary (3°)
- Secondary (2°)
- Primary (1°)
- Methyl
Drag a box over the question, just like in the extension. On a phone, tap it. Or press Snap & solve.
- Alkyl groups push electron density toward the positive carbon.
- More alkyl groups spread the charge out more.
- A 3° carbocation has three, so it is the most stable.
What is the major product of propene + HBr?
- 2-bromopropane
- 1-bromopropane
- Propane
- 1,2-dibromopropane
Drag a box over the question, just like in the extension. On a phone, tap it. Or press Snap & solve.
- H⁺ adds to C1, the carbon with more H's.
- That makes a more stable 2° carbocation on C2.
- Br⁻ adds to C2: 2-bromopropane.

Organic chemistry mechanism solver: follow the arrows
Mechanisms are where most orgo students get stuck. Every curved arrow shows an electron pair moving. Here's an SN2 reaction, the way the ochem mechanism solver walks through it.
- The hydroxide's lone pair attacks the carbon from the side opposite the bromine.
- At the same moment, the C–Br bond breaks and its electrons go to bromine.
- The OH is now bonded to carbon, bromide leaves, and the three H's flip like an umbrella in the wind.
SN1 or SN2?
- SN2: 1° or methyl carbon, strong nucleophile, one step, inversion.
- SN1: 3° carbon, weak nucleophile, carbocation first, a racemic mix.
E1 or E2?
- E2: strong base, one step, needs an H anti to the leaving group.
- E1: weak base and heat, carbocation first, Zaitsev product.
How to solve organic chemistry problems, step by step
Whether you use a solver or not, this five-step method works on almost any orgo problem.
- Step 1
Find the functional groups
Alkene, alcohol, halide, carbonyl? The groups tell you what can react.
- Step 2
Spot the reagent's job
Is it a nucleophile, a base, an electrophile or an oxidizer?
- Step 3
Pick the mechanism
SN1, SN2, E1, E2 or addition. Match it to the carbon and the conditions.
- Step 4
Push the arrows
Draw each arrow from an electron pair to where it goes, one step at a time.
- Step 5
Check the product
Count the carbons, check the charges, and look at regio- and stereochemistry.
How to check an organic chemistry answer
Any tool can slip, and so can you. These quick checks catch most mistakes, and they're good habits for the exam.
Count the carbons
The product should have the right number of carbons, unless the reaction adds or removes some.
Check the charges
Total charge stays the same from start to finish. Every atom should have a normal number of bonds.
Check regio and stereo
Did the H go to the right carbon? Is the product inverted, racemic, cis or trans?
Common organic chemistry mistakes to avoid
The H on the wrong carbon
In Markovnikov addition, H goes to the carbon that already has more H's.
Mixing up SN1 and SN2
Look at the carbon first. 1° carbons go SN2. 3° carbons go SN1.
Forgetting stereochemistry
SN2 inverts the carbon. SN1 gives a mix. Leaving it out costs points.

Organic chemistry FAQ
Is there a free organic chemistry solver?
Yes. QuizeGpt is a free orgo solver with steps. You get 10 answers a day for free, each with the mechanism and the rule behind it. No card is needed.
Is it an orgo solver and ochem solver?
Yes. Orgo and ochem are short for organic chemistry, so it works as an orgo AI solver and an ochem AI solver, for Organic Chemistry 1 and 2.
What organic chemistry problems can it solve?
Naming, SN1, SN2, E1 and E2, addition reactions, stereochemistry, aromatic reactions, carbonyl chemistry, synthesis and spectroscopy. It can also read a structure from a photo.
Can it explain reaction mechanisms?
Yes. As an organic chemistry mechanism solver, it describes each curved arrow, from the electron pair to the new bond, and explains why the reaction goes that way.
Can it predict the product of a reaction?
Yes. Give it the reactants and reagents, and the orgo reaction solver names the major product and explains why it's major, like Markovnikov's or Zaitsev's rule.
Can it help with synthesis problems?
Yes. As an organic chemistry synthesis solver, it plans a route step by step and explains what each reagent does, so you learn how to build the route yourself.
Can it read a drawn structure?
It reads clear photos and screenshots of structures. If a drawing is hard to read, type the name or the formula instead for the best result.
How accurate are the answers?
Like any organic chem solver, it can slip, so it shows every step for you to check. Count the carbons and check the charges on the product to catch mistakes.
Can it help with my organic chemistry homework?
Yes. It's more than an organic chemistry answer solver: it shows you how to solve each problem step by step. Use the steps to learn the pattern, then try the next one yourself. That's what helps on the exam.
Can I use it on an organic chemistry exam?
No. Keep QuizeGpt closed on exams, quizzes that count, and proctored tests. Use it for homework you're allowed help on, practice problems, and review after you submit.
