Question

The angular shape of molecule $O_3$ consists of :

• A. $1$ sigma and $1$ pi bond
• B. $2$ sigma and $1$ pi bond
• C. $1$ sigma and $2$ pi bond
• D. $2$ sigma and $2$ pi bond

Answer 1

The correct option is B $2$ sigma and $1$ pi bond

The molecule of $O_3$ is bent in shape with a bond angle of ${116.8}^0$, and equal $O-O$ bond length of $128pm$ on both sides of the central oxygen atom. The ozone molecule consists of $2$ sigma bonds and $1$ pi bond, as can be seen from the figure.

$\therefore O_3=2\sigma +1\pi bond$

Hence, option (B) is correct.
