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(|)(C)H-COOH`
D. `CH_(3)CH_(2)COOH`

Answer 1

Correct Answer - D
`underset((A))(CH_(3)CH_(2)-overset(O)overset(||)(C)-OH) overset(NH_(3))to underset((B))(CH_(3)CH_(2)CO overset(Theta)(O)overset(o+)(N)H_(4)overset(Delta)to underset((C))(CH_(3)-CH_(2)-) overset(O)overset(||)(C)-NH_(2) underset("Hofmann bromamide reaction") overset(Br_(2),KOH)toCH_(3)-CH_(2)-NH_(2)`.
