STANDARD Chemistry Free Radicals MCQ Question

Type: MCQ-conceptual-Medium

The increasing order of stability of the following free radicals is

A

(CH₃)₂ĊH < (CH₃)₃Ċ < (C₆H₅)₂ĊH < (C₆H₅)₃Ċ

B

(C₆H₅)₃Ċ < (C₆H₅)₂ĊH < (CH₃)₃Ċ < (CH₃)₂ĊH

C

(C₆H₅)₂ĊH < (C₆H₅)₃Ċ < (CH₃)₃Ċ < (CH₃)₂ĊH

D

(CH₃)₂ĊH < (CH₃)₃Ċ < (C₆H₅)₃Ċ < (C₆H₅)₂ĊH

Correct Answer

Option A

Detailed Explanation

The stability of free radicals is influenced by hyperconjugation and resonance. Alkyl radicals are stabilized by hyperconjugation, while aryl radicals are stabilized by resonance. Therefore, the order of stability is (CH₃)₂ĊH < (CH₃)₃Ċ < (C₆H₅)₂ĊH < (C₆H₅)₃Ċ.
