The dipeptide Gln-Gly on treatment with ...

The dipeptide Gln-Gly on treatment with `CH_(3)COCI` followed by aqueous work up gives :

A

Only `CH_(3)COOCH_(2)CH_(3)`

B

A mixture of `CH_(3)COOH` and `EtOH`

C

Only `CH_(3)COOH`

D

Only `EtOH`

Text Solution

Verified by Experts

The correct Answer is:
A

All aldehydes (with or without `alpha`-hydrogen) undergo Cannizzaro reaction in presence of aluminium ethoxide. The acid and alcohol formed react together to give the ester. This reaction is known as Tischenko's reaction.
`2CH_(3)CHO overset((EtO)_(3)AI)rarr CH_(3)COOH + C_(2)H_(5)OH rarr underset("Ethyl acetate")(CH_(3)COOC_(2)H_(5))`
