Question

The number of $s{p}^2-s$ sigma bonds is benzene are:

• A. 3
• B. 6
• C. 12
• D. none of these

Answer 1

Answer: (B)

6

Benzene has molecular formula $C_6{H}_6$ that is there is the presence of a double bond in between alternate carbon atoms and each carbon is attached to $two$ carbon atoms by means of a single bond and a double bond and a hydrogen atom by a single bond. So there are a total of $12$ sigma bonds and $3$ pi bonds in benzene.

The carbon atoms are bonded through $s{p}^2-S{p}^2$ overlap while six $C-H$ bond is formed by $s{p}^2-s$ sigma bond.

Thus there is $6$ $s{p}^2-s$ sigma bond.
