Question

The angular shape of ozone molecule (O3O_3) consists of:

A

1 sigma and 2 \pi bonds

B

2 sigma and 2 \pi bonds

C

1 sigma and 1 \pi bonds

D

2 sigma and 1 \pi bonds

Step-by-Step Solution

The ozone (O3O_3) molecule has an angular (bent) structure and is a resonance hybrid of two main canonical forms: O=O+−O−O=O^+-O^- and O−−O+=OO^--O^+=O. In its structure, the central oxygen atom is connected to one terminal oxygen atom by a double bond and to the other by a single bond. Since a single covalent bond consists of one σ\sigma bond, and a double bond consists of one σ\sigma and one π\pi bond, the O3O_3 molecule contains a total of 2 σ\sigma bonds and 1 π\pi bond.
