Whether the given compounds exhibit cis-trans isomerism or not is to be stated. Concept Introduction: Alkenes are unsaturated hydrocarbons that contain carbon-carbon double bonds. In a cis isomer, both the alkyl groups are on the same side of the C=C double bond whereas in trans isomers, the alkyl groups are on the opposite side of the double bond. These isomers can have different physical properties.

Answer 1

Question

Definition Definition Molecules that have multiple bonds between their carbon atoms. Alkenes are hydrocarbons with a double bond between two adjacent carbon atoms (R 2 C=CR 2 ), whereas alkynes are hydrocarbons with a triple bond between two adjacent carbon atoms R-C=C-R . These two groups are known as unsaturated hydrocarbons. They have fewer hydrogen atoms when compared with alkanes with same number of carbon atoms. The general molecular formula for an unsaturated hydrocarbon can be represented as C n H 2n +2 .
