STANDARD Chemistry Elimination Reactions MCQ Question
Type: MCQ-conceptual-Medium-Class 12
The ease of dehydrohalogenation of alkyl halide with alcoholic KOH is
A
3° < 2° < 1°
B
3° > 2° > 1°
C
3° < 2° > 1°
D
3° > 2° < 1°
Correct Answer
Option B
Detailed Explanation
In dehydrohalogenation, the stability of the resulting alkene determines the ease of reaction. Tertiary (3°) alkyl halides form more stable alkenes due to hyperconjugation and inductive effects, making them more reactive in dehydrohalogenation.
