Here we have to draw the possible structures of the cis-cycloalkanes, which has the chemical formula[tex]C_{7}H_{14}[/tex] having a 5-membered ring.
There will be two structures of the given molecule which is shown in the attached file.
The [tex]C_{7}H_{14}[/tex] molecules has a 5-membered ring the maximum number of carbon and hydrogen present in a 5-membered ring is [tex]C_{5}H_{10}[/tex]. Which reveals there will be two methyl group i.e. -CH₃. The -cis form of a compound reveals the position of a particular group will be on the same side in three dimension. Thus we have two -cis structures of [tex]C_{7}H_{14}[/tex] where the two methyl groups are present in the same direction in three dimensions.
The two cis-structures of the given molecule is shown in the attached image file.
