Ethylene dichloride and ethylidene chloride are isomeric compounds. The false statement about these isomers is that they

The number of all types of isomers of chlorobutane $(C_4H_9Cl)$ is:

Assertion : Alkylbenzene is not prepared by Friedel-Crafts alkylation of benzene.
Reason : Alkyl halides are less reactive than acyl halides.

The product $A$ is
