Hybridisation of carbonyl carbon in planar compounds

sp2sp^2 hybridisation

Bond angle around carbonyl carbon

Approximately 120°120°

Functional group in aldehydes

-CHO (aldehyde group)

General formula for aldehydes

RCHO

Position of carbonyl group in aldehydes

Always at the end of the carbon chain

General formula for ketones

RCOR'

Position of carbonyl group in ketones

Never at the end; always internal

Functional group in carboxylic acids

-COOH (carboxyl group)

General formula for carboxylic acids

RCOOH

Carboxylic acids form what through hydrogen bonding?

Dimers (pairs of molecules)

Reaction: carboxylic acid + alcohol →

Ester + water (esterification/condensation)

General formula for esters

RCOOR'

How to name esters (structure)

Alkyl group from alcohol + acid part as '-oate'

Characteristic smell of esters

Pleasant, fruity smells

Boiling point order: carboxylic acids, aldehydes, esters

Carboxylic acids > aldehydes/ketones > esters
