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

Options

  1. Aσ = 18 ,   π = 3
  2. Bσ = 21 ,   π = 4
  3. Cσ = 23 ,   π = 5
  4. Dσ = 16 ,   π = 4

Correct answer

B. σ = 21 ,   π = 4

Step-by-step 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.
