Question

(i) What type of reaction takes place between ethane and chlorine to form monochloroethane?
(ii) The reaction between ethene and chlorine forms only one product. Name the type of the reaction.
(iii) (a) Draw the structural formula of ethene.
(b) What is the feature of the ethene structure, which allows ethene to react with chlorine in the way it does?

Answer 1

(i) Substitution reaction takes place between ethane and chlorine to form monochloroethane.

(ii) When the reaction between ethene and chlorine forms only one product, then this type of the reaction is called an addition reaction.

(iii) (a) The structural formula of ethene is:


(b) The carbon-carbon double bond allows ethene to participate in an addition reaction with chlorine.
