Question

How many sigma and pi-bonds are there in the molecule of dicyanoethene (\( \text{CH}_2 \text{CH} \text{CN} \))?

• A. 3 sigma and 3 pi
• B. 5 sigma and 2 pi
• C. 7 sigma and 5 pi
• D. 2 sigma and 3 pi

Hint:

Sigma bonds are single bonds, while pi bonds are formed by the sideways overlap of p-orbitals in double and triple bonds.

Answer 1

The Correct Option is A

In dicyanoethene, the sigma and pi bonds can be counted based on the bonding between carbon atoms and the number of double bonds.
