1
New cards
Oxidizing agents for alcohols

Acidified potassium dichromate or potassium manganate.

Color change: orange to green (Cr₂O₇²⁻ → Cr³⁺).

2
New cards
Partial oxidation of primary alcohols

Forms aldehydes.

Conditions: heat and distillation, excess alcohol.

Aldehyde is distilled off.

3
New cards
Complete oxidation of primary alcohols

Forms carboxylic acids.

Conditions: heat under reflux, excess oxidizing agent.

Uses reflux condenser.

Forms ketones.

Conditions: heat under reflux.

Uses acidified potassium dichromate.

5
New cards
Oxidation of tertiary alcohols

Does not occur.

No H on carbon with –OH group.

Tertiary alcohols resist oxidation.

New cards
Function of distillation and reflux

Distillation: separates aldehyde.

Reflux: ensures complete oxidation by prolonged contact.
