Among the molecules of ethane, ethylene,...

Among the molecules of ethane, ethylene, and acetylene, the `C-H` bond energy is the

A

(1) highest in ethane

B

(2) highest in ethylene

C

(3) highest in acetylene

D

(4) same in all the three

Text Solution

Verified by Experts

The correct Answer is:
C
The order of `C-H` bond energy is
`C(sp) - H gt C (sp^(2))-H gt C (sp^(3))-H`
Thus, `CH = overset(sp)(C )-H gt CH_(2) = overset(sp^(2))(CH)-H gt CH_(3)overset(sp^(3))(CH_(2))-H`
