Q 1 :    

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).

 

Assertion (A): CH2=CH-CH2-Cl is an example of allyl halide.

 

Reason (R): Allyl halides are the compounds in which the halogen atom is attached to sp2 hybridised carbon atom.

 

In the light of the above statements, choose the most appropriate answer from the options given below:                [2024]

  • (A) is true but (R) is false

     

  • Both (A) and (R) are true but (R) is not the correct explanation of (A)

     

  • (A) is false but (R) is true

     

  • Both (A) and (R) are true and (R) is the correct explanation of (A)

     

(A)

sp3 carbon next to C=C is called allylic carbon. A halide carrying halogen on allylic carbon is called an allylic halide. CH2=CH-CH2-Cl is hence an allylic halide. Halides containing a halogen atom attached to an sp2 carbon of an aromatic ring are called aryl halides and those containing a halogen atom attached to an sp2 carbon of a C=C bond are called vinyl halides.
