The increasing basicity order of the following compounds is :
(A) `CH_(3)CH_(2)NH_(2)`
(B) `CH_(3)CH_(2)overset(underset(|)(CH_(2)CH_(3)))(NH)`
(C ) `H_(3)C-overset(underset(|)(CH_(3)))(N)-CH_(3)`
(D) `Ph-overset(underset(|)(CH_(3)))(N)-H`

A

`(D) lt (C) lt (A) lt(B)`

B

`(A) lt (B) lt (D) lt(C)`

C

`(A) lt (B) lt (C) lt(D)`

D

`(D) lt (C) lt (B) lt(A)`

Text Solution

Verified by Experts

The correct Answer is:
D
`underset((D))underset("delocalised lone pair")(Ph-overset(CH_(3))overset(|)N-H) lt underset((C))underset("steric hindrance and less hydration energy")(CH_(3)-overset(CH_(3))overset(|)(N)-CH_(3)) lt underset((B))(CH_(3)CH_(2)-overset(CH_(2)CH_(3))overset(|)NH) lt underset((A))(CH_(3)CH_(2)NH_(2))`
