Answer:
The cis-4-nonene molecule contains a total of 26 bonds. There are 8 non-H bonds, 1 multiple bond, 5 rotary bonds, and 1 double bond.
The carbon atoms in the chemical structure are located at the corners and the hydrogen atoms attached to the carbon atoms are not indicated, each carbon atom are considered to be associated with enough hydrogen atoms to provide the carbon atom with four bonds. Only the hydrogens attached to the double bond are specified to identify the cis configuration.
It is called the cis isomer since it has the hydrogens on the same side in the double bond.
