There are 23 σ bonds in a molecule of 2-propylpent-1-ene.

#### Explanation:

The structural formula of 2-propylpent-1-ene is

Every $\text{C-C}$ and every $\text{C-H}$ single bond is a σ bond.

Every $\text{C=C}$ double bond consists of a σ bond and a π bond.

There are 6 $\text{C-C}$ bonds, 16 $\text{C-H}$ bonds, and 1 $\text{C=C}$ bond.

Thus, there are 23 σ bonds in the molecule.
