Esterification: organic acid + alcohol ester + water usually easy to spot- look for water!

Saponification: ester + base soap + alcohol

Fermentation Glucose alcohol + CO 2

Polymerization- formation of long chains of monomers covalently bonded as polymers • Two types: • Addition polymerization- joining small monomers of unsaturated hydrocarbons • Condensation polymerization- bonding monomers by removing water between them

Organic Reactions • Combustion- burning of hydrocarbon with oxygen to produce heat, CO 2, and H 2 O • Substitution- one atom or atoms is replaced by another atom or group of atoms • Addition- other atoms attach to carbons that are in a double or triple bond (removes multiple bond) • Esterification- organic acid+alcohol ester + water • Saponification- ester + base soap + alcohol • Fermentation- glucose breaks down into alcohol, CO 2, and energy • Polymerization- small organic units bond together to form very large molecules
