The index of hydrogen deficiency (IHD) of benzene is

A

4

B

6

C

2

D

3

Text Solution

Verified by Experts

The correct Answer is:
4
Molecular formula of benzene is `C_(6)H_(6)`
`IHD=sum(n(v-2))/(2)+1=(6(4-2)+6(1-2))/(2)+1`
`=3+1=4`
IHD for banzene is 4 due, to three `pi` bonds and one cyclic structure.
