About ReactionWeb.io

An interactive database of organic chemistry reactions designed for quick reference and efficient studying.

If you've ever needed to quickly check what solvent a reaction uses, whether it's concerted or stepwise, or just wanted to see a mechanism without digging through a textbook, this site is for you.

What You'll Find Here

The site contains 100+ organic chemistry reactions organized by functional group transformations. Each reaction includes:

Reaction conditions: Temperature requirements, solvent polarity/proticity, pH environment, atmosphere requirements
Mechanism information: Concerted vs stepwise, rate-determining step, structured explanations
Selectivity data: Regioselectivity, stereoselectivity, stereospecificity with specific values (Markovnikov, anti, retention, etc.)
Mechanism videos: Step-by-step video explanations for most reactions
Overview content: Detailed explanations in consistent, scannable format
Related reactions: Similar transformations and alternative reagents

How to Use the Site

1. The Reaction Web (Main Page)

Structure Search

Look up experimental data for compounds (melting point, appearance, density, etc.) with direct links to find spectral data and safety data sheets. Focused on the properties students actually need for lab reports.

Filter Options

Show/hide functional groups to simplify the network view

Why This Exists

Traditional reaction resources have two problems: textbooks bury simple answers in lengthy explanations, while reaction maps/sheets lack the details you need when you need them. ReactionWeb.io puts everything in one place with consistent formatting.

          The site is particularly useful for:
          Quick lookups during problem sets ("what temperature does this need?")
Exam review (all mechanisms in consistent format with videos)
Synthesis planning (see all ways to make/transform a functional group)
Understanding reaction patterns (similar reactions are linked and comparable)
Lab report writing (get experimental data quickly without wading through databases)

        

Design Philosophy

The site is intentionally information-dense. We assume you already understand basic organic chemistry concepts and just need the specific details. The consistent format across all reactions means once you learn to read one page, you can quickly scan any other.

The interconnected nature also helps with learning - you'll often discover useful transformations just by exploring related reactions. It's pedantic by design, showing distinctions between similar reactions that textbooks might gloss over.

Getting Started

Start by clicking on a functional group you're interested in, like "Alcohol" or "Ketone". The tables will show you all the chemistry available. Pick a reaction that interests you and click through to see the full details. The more you explore, the more connections you'll discover.
