Predict products for common reaction patterns

What you’ll practice

This quiz trains you to recognize common reaction patterns and predict the most likely products, not just memorize reagent lists. Expect a mix of straightforward transformations and multi-step reasoning where one detail changes the outcome.

Each question uses 4 options and there’s no timer, so you can slow down to check mechanisms, then speed up as you gain confidence. You can also choose your question count and difficulty before starting to tailor practice to quick drills or full-length sessions.

Common pitfalls to avoid

Many wrong answers are built around classic traps: picking the minor product, ignoring rearrangements, or forgetting how conditions shift selectivity. Watch especially for regiochemistry, stereochemistry, and functional-group compatibility.

How the difficulty stays balanced

Difficulty is mixed on purpose: easier items reinforce core patterns, while tougher ones test edge cases and competing pathways. As you adjust difficulty and question count, you can focus on fundamentals first or push into more nuanced reagent/condition choices.

Tips for higher scores

• Identify the functional group and the key bond change before looking at the options
• Check regiochemistry and stereochemistry explicitly (don’t assume)
• Look for competing reactions (elimination vs substitution, over-oxidation, etc.)
• Treat conditions as clues: solvent, acid/base, heat, and equivalents matter
• Eliminate “impossible” products first (wrong oxidation state or incompatible groups)
