Q 1 :    

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

 

Assertion (A): ${\mathrm{CH}}_2=\mathrm{CH}-{\mathrm{CH}}_2-\mathrm{Cl}$ is an example of allyl halide.

 

Reason (R): Allyl halides are the compounds in which the halogen atom is attached to $s{p}^2$ 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)
