Assertion `(A)`: `PhBr` is less reactive than `C_(2)H_(5)Br` towards `SN` reactions.
Reason `(R): The forces of attrafction between `RX` and `H_(2)O` molecules are weaker than those present between the molecules of `RX` and water molelcules separate,u.

A

Both `(A)` and `(R)` are true and `(R0` is the correct explanation of `(A)`.

B

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

C

`(A) is true but `(R)` is false.

D

`(A) is false but `(R)` is true.

Text Solution

Verified by Experts

The correct Answer is:
`b`
Correct explanation:
Due to resonance `(C-Br)` bond in `PhBr` is a little stronger than `(C-Br)` bond in `C_(2)H_(5)Br`
