Tool overview

Explore the use cases, workflow, and key things to know.

Show electron movement

Name the source and destination of each curved arrow.

Audit structures

Review valence, formal charge and atom conservation step by step.

Keep the scope explicit

A schematic proposal is not a measured rate law or proof of the dominant pathway.

Concept reference

Reaction Mechanism Figure Generator: a worked example

This reaction mechanism figure uses a proton transfer from hydrogen chloride to acetate. One electron-pair arrow runs from the negatively charged oxygen toward hydrogen; the other runs from the H–Cl bond toward chlorine. Products are acetic acid and chloride, preserving atoms and the total charge of −1. The example is illustrative rather than a condition-specific kinetic model.

Reaction Mechanism Figure Generator: plan the content

A reaction mechanism figure must distinguish the straight reaction arrow from curved electron arrows. Start electron-pair arrows at a lone pair or bond and end them at the stated acceptor or bond-forming location.

State the actual step

Give the reaction mechanism figure generator the specific reacting species and protonation states rather than a vague reaction name.

Use one electron convention

A full-headed curved arrow represents an electron pair. Radical single-electron movement needs a different convention and a clear explanation.

Review products independently

Check the resulting structure after each bond change. A neat arrow cannot rescue an invalid valence or missing atom.

Common mistakes in a reaction mechanism figure

Starting an arrow at a positive proton

In the reference, the electron pair starts at the base’s oxygen. The proton accepts electron density; it is not the source of that pair.

Forgetting the breaking bond

Proton transfer from H–Cl also requires the bonding electron pair to move to chlorine. Omitting that arrow leaves the electron bookkeeping incomplete.

Confusing plausibility and validation

A reaction mechanism figure can depict a plausible route without proving it dominates under specific solvent, temperature or concentration conditions.

  1. 1

    Supply structures and intended changes

    Tell the reaction mechanism figure generator the exact species, formal charges and proposed step.

  2. 2

    Draft arrows with stated origins

    Describe each electron source and destination and keep the overall reaction arrow visually distinct.

  3. 3

    Check the reaction mechanism figure

    Review valence, atom and charge balance, intermediate identity and any stereochemical claims before using the draft.

Example brief for a reaction mechanism figure

Create a reaction mechanism figure for acetate accepting a proton from HCl to form acetic acid and chloride. Draw one single-headed curved arrow from an oxygen lone pair to hydrogen and one from the H–Cl bond to chlorine. Distinguish these from the straight reaction arrow. Show valid valence, conserve all atoms and total charge −1, and identify the scheme as an illustrative acid–base step.

Reaction Mechanism Figure Generator: common questions

What does the reaction mechanism figure generator do?

It drafts a chemistry illustration from your specified mechanism. It does not discover or computationally validate a reaction pathway.

Where should curved electron arrows begin?

For electron-pair arrows, begin at a lone pair or a bond. The arrow must account for an actual electron source.

What is the difference between a curved arrow and a reaction arrow?

A curved arrow tracks electron movement within a proposed step. A straight reaction arrow connects reactants with products or successive stages.

Does the example conserve charge?

Yes. Acetate plus neutral HCl has total charge −1; neutral acetic acid plus chloride also has total charge −1.

Can the reaction mechanism figure generator show radicals?

You can describe a radical scheme, but single-electron arrow conventions and the chemical validity require careful review. The reference example uses only electron-pair arrows.
