Number of bonds in benzene :

A)  \[6\,\sigma \] and \[3\,\pi \]    

B)  \[12\,\sigma \] and \[3\,\pi \]

C)  \[3\,\sigma \] and \[12\,\pi \]   

D)  \[6\,\sigma \] and \[6\,\pi \]

Correct Answer: B

Solution :

Key Idea: The first bond between any two atoms is \[\sigma \] and rest are \[\pi \] bonds. Draw the structure of benzene and count \[\sigma \]and \[\pi \] bonds. \[\therefore \] It has 12 a and 3 n bonds.
