Organic Chemistry Practice (Interactive)

Intuition

Organic chemistry practice is like learning a new language, functional groups, reaction mechanisms, and nomenclature require systematic study: Organic practice develops skills in predicting reactivity, drawing mechanisms, and designing synthesis routes

Why it matters: Organic chemistry is essential for pharmaceuticals, polymers, and understanding biological molecules

The key insight: Organic practice develops skills in predicting reactivity, drawing mechanisms, and designing synthesis routes

Common Mistakes

Confusing addition with condensation polymerisation: Addition polymerisation opens double bonds (no by-product). Condensation polymerisation joins monomers with elimination of a small molecule (water, HCl). Don’t assume all polymers form the same way.

Forgetting that Markovnikov’s rule applies to HX addition: When HX adds to an unsymmetrical alkene, H goes to the carbon with more H atoms. This gives the more stable carbocation intermediate.

Mixing up elimination with substitution: Elimination removes atoms to form a double bond. Substitution replaces one atom/group with another. Both can compete under the same conditions.
