Text Solution

Verified by Experts

The correct Answer is:
B
Rate of SN1 `alpha` stability of carbocation
`alpha +I, +M,` HC effect
`{:((i)CH_(3)-overset(Cl)overset(|)Ch-CH_(2)CH_(3)toCH_(3)-overset(o+)CH-CH_(2)-CH_(3)),((ii)PH-CH_(2)-underset(Cl)underset(|)(CH)-CH_(3) to PH-CH_(2)-overset(o+)CH-CH_(3)),((iii) CH_(3)-overset(Cl)overset(|)underset(OCH_(3))underset(|)C-CH_(3)toCH_(3)-underset(OCH_(3))underset(|)overset(o+)C-CH_(3)),((iv)CH_(3)-CH_(2)-CH_(2)-Clto CH_(3)-CH_(2)-CH_(2)^(+)):}`
