Recall that an alkene is a hydrocarbon containing at least one carbon-carbon double bond, which consists of one sigma (\(\sigma\)) bond and one pi (\(\pi\)) bond.
Understand that the molecule has no rings or triple bonds, so all bonds are either single (\(\sigma\) only) or double (one \(\sigma\) and one \(\pi\)).
Note that each carbon-carbon single bond contributes one \(\sigma\) bond, and each carbon-carbon double bond contributes one \(\sigma\) and one \(\pi\) bond.
Since the molecule has 10 \(\sigma\) bonds total, count how many of these are from the carbon-carbon bonds and how many from carbon-hydrogen bonds, keeping in mind the structure of alkenes.
Use the relationship between the number of \(\sigma\) and \(\pi\) bonds in alkenes to determine the number of \(\pi\) bonds, knowing that each double bond adds exactly one \(\pi\) bond.
