Question
Assertion (A): CH2=CH−CH2−Cl is an example of allyl halideReason (R): Allyl halides are the compounds in which the halogen atom is attached to sp2 hybridised carbon atom.
Solution
The assertion (A) is correct. CH2=CH−CH2−Cl is indeed an example of an allyl halide. Allyl halides are organic compounds in which a halogen atom is bonded to an allyl group, which is a carbon-based group with the formula R-CH2-CH=CH2, where R can be any other group of atoms.
However, the reason (R) is incorrect. In allyl halides, the halogen atom is not attached to an sp2 hybridised carbon atom, but rather to an sp3 hybridised carbon atom. The sp2 hybridised carbon atoms are involved in the double bond in the allyl group, but the halogen is attached to the single-bonded carbon atom, which is sp3 hybridised.
So, while the assertion is correct, the reason given is not the correct explanation.

In alkyl halides, the halogen atom is bonded to an alkyl group (R).They form a homologous series represented by CnH2n+1X. They arefurther classified as primary, secondary or tertiary according to thenature of carbon to which halogen is attached. If halogen is attached toa primary carbon atom in an alkyl halide, the alkyl halide is calledprimary alkyl halide or 1° alkyl halide. Similarly, if halogen is attachedto secondary or tertiary carbon atom, the alkyl halide is calledsecondary alkyl halide (2°) and tertiary (3°) alkyl halide, respectively.
