Question

Is it true that all alkenes show cis-trans isomers?​

Answer 1

Answer:

Alkenes with a C=CH2 unit do not exist as cis-trans isomers. ... Alkenes of the type R–CH=CH–R can exist as cis and trans isomers; cis if the two R groups are on the same side of the carbon-to-carbon double bond, and trans if the two R groups are on opposite sides of the carbon-to-carbon double bond.
