Interpretation − To identify the cis trans isomer.
Concept Introduction
Cis-trans isomers: When molecules have restricted rotation around double bond and two non identical groups around each carbon of double bond. They show cis trans isomers.
Cis isomer: When similar group present on same side of double bond.
Trans isomers: When similar group present on opposite side of double bond.
Explanation of Solution
Structure first has methyl group on same side of double bond and hydrogen on same side of double bond; hence it is a cis isomer.
Structure second also has methyl group on same side and hydrogen group on same side of double bond, it is also a cis isomer.
The structure of cis trans isomers will be:
Hence the given structures are not cis trans isomer.
