Arrange the following free radiacals in order of decreasing stability.
Methyl (I), Vinyl(II), Allyl(III), Benzyl(IV)

A

`IgtIIgtIIIgtIV`

B

`IIIgtIIgtIgtIV`

C

`IIgtIgtIVgtIII`

D

`IVgtIIIgtIgtII`

Text Solution

Verified by Experts

The correct Answer is:
D
Benzyl and allyl free radicals are resonance stablised and are more stable than alkyl free radicals. Methyl radical is less stable as the odd electron is present on `sp^(3)` C-atom and shows hyperconjugation.

Vinyl is least stable as number resonating structure are least.
`:.` Order is
Benzyl (IV) `gt` Allyl(III) `gt` Methyl(I) `gt` Vinyl (II)
