Chemical Bonding And Molecular Structure

Question
CBSEENCH11008397
Wired Faculty App

The angular shape of ozone molecule (O3) consists of 

  • 1 sigma and 2 pi bonds

  • 2 sigma and 2 pi bonds

  • 1 sigma and 1 pi bonds

  • 2 sigma and 1 pi bonds

Solution

D.

2 sigma and 1 pi bonds

Single bond contains = 1 σ bond
Double bond contains = 1 σ bond + 1 π bond
Triple bond contains = 1σ  bond + 2 π bond
The molecule of O3 is bent with an angle of 116.8o and equal O-O distance of 128 pm. The ozone molecule consists of 2 sigma bond and 1 pi bond.
