On C coom other
Dicarboxylic acid compound containing two carboxyl
groups
eg n o E E o n OOH
Oxylic acid My 204
Saltsof carboxylic acids
Carboxylic acids acidic due to hydrogen in COOH
eg
CH COOH CHz Coo Ht
Do not draw bond between
Chz c sodium l O as it is ionic
pay covalent
Eg Ear between magnesium carbonate oxalis acid
no É C on
Mgcoz o i I o Mg 130
, Properties
Boiling points
as size also due to vaw
Alcohol lower bp
Carboxylic acid Higher bp
Both have H Bonds but C A can produce a
dimer between two molecules
of itself
Diversification Ethanoic acid
aug 5 _c cuz
o
WINE
Doubles size molecule doubles RMM
value
of
This means is doubled increasing
of
no e
the strength of vdw between neighbouring
molecules
Doesn't occur in alcohols as H Bonds not
strong enough
