The total number of σ and π - bonds present in the following compound are

The total number of σ and π-bonds present in the following compound are

  1. σ=18, π=3
  2. σ=21, π=4
  3. σ=23, π=5
  4. σ=16, π=4

Solution

Count the single bonds and double bonds.

Single bonds are called σ-bonds and double bond contain one σ-bond and a π-bond.

Benzene ring contain three pi bonds in the ring and one more pi bond is carbonyl group of ester. Remaining all are sigma bonds.
