Question

In a cyclotrimetaphosphoric acid molecule, how many pi and sigma bonds are present?

• A. 3 pi bonds; 9 sigma bonds
• B. 6 pi bonds; 6 sigma bonds
• C. 3 pi bonds; 15 sigma bonds
• D. 3 pi bonds; 12 sigma bonds

Answer 1

The correct option is C 3 pi bonds; 15 sigma bonds

The structure of cyclotrimetaphosphoric acid, $(HP{O}_3{)}_3$ is:


It contains 3 pi bonds and 12 sigma bonds.
