Consider the following three amines, (...

Consider the following three amines,
(1) `CH_(3)CH_(2)-overset(* *)NH_(2)`
(2)`CH_(2)=CH-overset(* *)NH_(2)`

Arrange C-N bond length of these compounds in decreasing order :

A

`1gt2gt3`

B

`1gt3gt2`

C

`3gt2gt1`

D

`2gt3gt1`

Text Solution

Verified by Experts

The correct Answer is:
A
No resonance in (I). Due to resonance in (II) (-) bond get converted into (=) bond. More resonance in (III).
