Define secondary alcohol
The carbon attached to the OH is attached to two other carbon atoms
Define tertiary alcohol
The carbon attached to the OH is attached to three other carbon atoms
How is an aldehyde formed?
Primary alcohol is mixed with an oxidising agent
2 H atoms are removed
What is a suitable oxidising agent?
Acidified potassium dichromate
K2Cr2O7
How is a ketone produced?
A secondary alcohol is mixed with an oxidising agent, 2 H atoms are removed
How is a carboxylic acid produced?
An aldehyde is mixed with an oxidising agent
An oxygen atom is added
What apparatus is used for aldehydes, ketones and carboxylic acids?
Distillation apparatus - aldehyde and ketones
Reflux apparatus - carboxylic acids
Name and explain the two ways to distinguish between aldehydes and ketones
Tollen's Reagent
Aldehydes are reducing agents
Ag+ ions are reduced to metallic silver
There is a silver mirror in a positive test
Fehling's Solution
Aldehydes are reducing agents
Cu2+ is an oxidising agent, they react
There is a brick red precipitate in a positive test
