Question

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)COOH`
B. `CH_(3)CH_(2)CH_(2)COOH`
C. `CH_(3)underset(CH_(3))underset(|)CHCOOH`
D. `CH_(3)CH_(2)COOH`

Answer 1

Correct Answer - D
(d) The final prodcut ethyl amine `(C_(2)H_(5)NH_(2))` shows that the corresponding acid have one carbon atom more. It is therefore, `CH_(3)CH_(2)COOH.`
`underset((A))underset()(CH_(3)CH_(2)COOH)overset(NH_(3))rarrunderset((B))underset()(CH_(3)CH_(2)COONH_(4))overset("heat")rarrunderset((C))underset()(CH_(3)CH_(2)CONH_(2))overset(Br_(2)//KOH)rarrunderset("Ethylamine")underset()(CH_(3)CH_(2)NH_(2))`
