#1
Front (Question)

What is a carboxylic acid derivative?

Back (Answer)

Compound that can be hydrolysed to form the parent carboxylic acid chain

#2
Front (Question)

Acyl chloride functional group

Back (Answer)

COCl

#3
Front (Question)

How are acid anhydrides formed?

Back (Answer)

Removal of water from two carboxylic acid molecules

#4
Front (Question)

Esterification

Back (Answer)

Reaction of an alcohol with a carboxylic acid to form an ester Requires conc H2SO4 catalyst

#5
Front (Question)

Acid hydrolysis of esters

Back (Answer)

Ester heated under reflux with dilute aqueous acid Ester broken down by water - acid acts as a catalyst Carboxylic acid and alcohol formed

#6
Front (Question)

Alkaline hydrolysis of esters (SAPONIFICATION)

Back (Answer)

Irreversible Ester heated under reflux with OH- ion s Forms carboxylate ion and alcohol

#7
Front (Question)

Carboxylic acid -> Acyl chloride

Back (Answer)

Heat with SoCl2

#8
Front (Question)

Carbonyls that can react with phenol to form esters

Back (Answer)

Acyl chlorides Acid anhydrides

#9
Front (Question)

Acyl chloride -> carboxylic acid

Back (Answer)

Add H2O - HCl is also formed

#10
Front (Question)

Which is more reactive - acid anhydride or acyl chloride?

Back (Answer)

Acyl chloride
