An orgainc compound A upon reacting with...

An orgainc compound A upon reacting with `NH_(3)` gives `B` On heating `B` give `C.C` in presence `KOH` reacts with `Br_(2)` to yield `CH_(3)CH_(2)NH_(2) A` is .

A

`CH_(3)-underset(CH_(3))underset(|)(CHCOOH)`

B

`CH_(3)CH_(2)COOH`

C

`CH_(3)COOH`

D

`CH_(3)CH_(2)CH_(2)COOH`

Text Solution

Verified by Experts

The correct Answer is:
B
`CH_(3)-underset((A))(CH_(2))-COOHoverset(NH_(3))rarrCH_(3)-underset((B))(CH_(2))-COONH_(4)overset(Delta)rarrCH_(3)-underset((C))(CH_(2))-COONH_(2)`
`underset("Hoffmann bromamide reaction")overset(KOH+Br_(2))rarrCH_(3)-underset(("Ethylamine"))(CH_(2))-NH_(2)`
