Alcohols
- Primary Alcohols
- RCH2OH
- RCHO + H2O
- RCOOH
- Carboxylic Acid
- Aldehyde
- Using Schiff Reagent
if it turns magenta
quickly it's an
aldehyde
- Heated under reflux with
excess KCr2 and H2So4
- reflux prevents aldehyde
from escaping before it can
oxidise to a carboxylic acid
- excess KCr2 ensure
there's enough agent
to fully oxidise to
COOH
- distilled will give an
aq. solution
- Secondary Alcohols
- RCHOH
- RCOR + H20
- Ketone
- Tertiary Alcohols
- RCOH
- Oxidising agent
- Potassium Dichromate
- (Cr2O7)2-
- Turns from orange to green
- Test for alkenes
- Add Bromine Water and if turns
colourless it is an alkene as
alkanes can't add to their
structure.
