Question

Draw the structure(s) of the cis-cycloalkanes with the chemical formula c7h14 that contain a 5-membered ring.

Answer 1

Here we have to draw the possible structures of the cis-cycloalkanes, which has the chemical formula$C_{7}H_{14}$ having a 5-membered ring.

There will be two structures of the given molecule which is shown in the attached file.

The $C_{7}H_{14}$ molecules has a 5-membered ring the maximum number of carbon and hydrogen present in a 5-membered ring is $C_{5}H_{10}$. 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 $C_{7}H_{14}$ 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.
