$C_6H_6$,
$C_6H_6$,
✓
Answer
The $\sigma$ and $\pi$ bonds are indicated below:
$C_6H_{12}$ can be either:
Straight chain compound
$H_3C-H_2C-H_2C-HC+CH-CH_3$
$\begin{matrix}6\text{C} - \text{C} & \sigma- \text{ bonds}\\12 \text{C} - \text{H} & \sigma-\text{bonds} \\ 1\text{C}-\text{C} & \pi-\text{bond}\end{matrix}\Bigg\}$ Other straight chain isomers will also have the same no. of $\sigma$ and $\pi$-bonds.
