16
Q

Carboxylic acid + alcohol + strong acid catalyst

A

Fischer esterification, ester is formed. (esters can also be formed from acyl chloride, which is more reactive because cl is a better leaving group).

17
Q

Ester + alcohol?

A

other type of ester is formed, transesterification

18
Q

Epoxide ring + nucleophile + acid catalyst

A

Epoxide ring opening, alcohol is formed after protonation. In acidic conditions, the more substituted end is attacked.

19
Q

Carboxylic acid + SOCl2?

A

Formation of acyl chloride, a very reactive derivative of carboxylic acids.

20
Q

Acyl chloride + alkoxide (deprotonated alcohol)?

A

Ester is formed

21
Q

Acyl chloride + deprotonated carboxylic acid?

A

Anhydride synthesis

22
Q

Ester + amine?

A

Amide synthesis

23
Q

2 equivalents of (usually) the same ester?

A

Claisen condensation, another type of ester is formed

24
Q

Ester + LiAlH4

A

Reduction of esters, alcohol is formed.

25
Q

Amide + LiAlH4

A

Reduction of amides, amine is formed
