Question

How many $\sigma$ and $\pi$ bonds are present in salicylic acid?

• A. $12\sigma$ and $4\pi$
• B. $16\sigma$ and $4\pi$
• C. $18\sigma$ and $2\pi$
• D. $16\sigma$ and $2\pi$

Answer 1

The correct option is A $12\sigma$ and $4\pi$

A double bond contain 1 $\sigma$ and 1 $\pi$ bond.

Total sigma bond $=7{\sigma }_{C-C}+2{\sigma }_{O-H}+3{\sigma }_{C-O}=12\sigma$ bond.

Total pi bond $=3{\pi }_{C-C}+1{\pi }_{C-O}=4\pi$ bond

So, correct option is A.
