Answer:
In cis configuration, the methyle group are placed on the same side of the Carbon atoms
Step-by-step explanation:
Cis tran isomerism is also called transformational are term used in organic chemistry.
Cis and Trans are all latin words that means "the side of" or "the other side of".
in cis isomerism, the functional groups e.g methyl or carboxyl groups are situated on the same side of the bond. Here rotation around the bond is highly restricted.
In trans, the functional groups are located at opposite sides of the bond. This configuration allows less restriction around the bond, as opposed to cis.
