The corrent order of `S_(N)2//E_(2)` ratio for the % yield of product of the following halide is
(P) `CH_(3)-CH_(2)-underset(I)underset(|)overset(Ph)overset(|)C -CH_(3)`
(Q) `CH_(3)-underset(Ph)underset(|)CH-underset(I)underset(|)CH -CH_(3)`
(R) `CH_(3) -CH_(2) -I`
(S) `CH_(3)CH_(2)-underset(I)underset(|)CH -CH_(3)` .

A

`RgtSgtQgtP`

B

`RgtQgtSgtP`

C

`PgtRgtSgtQ`

D

`QgtPgtRgtS`

Text Solution

Verified by Experts

The correct Answer is:
A
Rate of `SN_(2)` reaction `1^(@)gt 2^(@) gt3^(@)` as Beta- branching increases
steric crowding increases in transition state so it makes less stable transition state .
