Question

Assertion: Rate of reaction of alkyl halide in Williamson’s synthesis reaction is 1°RX > 2°RX > 3°RX. Reason: It is a type of bimolecular substitution reaction (SN2). (A) If both assertion and reason are true and reason is the correct explanation of assertion (B) If both assertion and reason are true but reason is not the correct explanation of assertion (C) If assertion is true but reason is false (D) If both assertion and reason are false

Williamson's synthesis occurs by S N 2 mechanism and primary alkyl halides are most reactive in S N 2 reactions.

Q. Assertion: Rate of reaction of alkyl halide in Williamson’s synthesis reaction is 1 $^{\circ}$ RX > 2 $^{\circ}$ RX > 3 $^{\circ}$ RX.
Reason: It is a type of bimolecular substitution reaction $(S_{N} 2)$ .

If both assertion and reason are true and reason is the correct explanation of assertion

If both assertion and reason are true but reason is not the correct explanation of assertion

If assertion is true but reason is false

If both assertion and reason are false

Williamson's synthesis occurs by $S_{N} 2$ mechanism and primary alkyl halides are most reactive in $S_{N} 2$ reactions.

Q. Assertion: Rate of reaction of alkyl halide in Williamson’s synthesis reaction is 1∘RX > 2∘RX > 3∘RX. Reason: It is a type of bimolecular substitution reaction (SN​2).
