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 :

1. Both (A) and (R) are true and (R) is the correct explanation of (A)
2. (A) is false but (R) is true
3. (A) is true but (R) is false
4. Both (A) and (R) are true but (R) is not the correct explanation of (A)

Correct answer: (A) is true but (R) is false

Solution

The assertion is correct because CH2=CH-CH2-Cl is indeed an allyl halide, as it has a halogen attached to a carbon adjacent to a double bond. However, the reason is incorrect because in allyl halides, the halogen is attached to a carbon that is sp3 hybridized, not sp2.
