The angular shape of ozone molecule (O3) consists of:

1. 1 sigma and 2 pi bonds
2. 2 sigma and 2 pi bonds
3. 1 sigma and 1 pi bonds
4. 2 sigma and 1 pi bonds

Correct answer: 2 sigma and 1 pi bonds

Solution

The ozone molecule (O3) has a resonance structure where one oxygen forms a double bond (1 sigma and 1 pi bond) with the central oxygen, and the other forms a single bond (1 sigma bond). Thus, there are 2 sigma and 1 pi bonds in total.
