Select the correct option:
A
(A) < (B) < (C) < (D)
B
B) < (A) < (D) < (C)
C
(A) < (B) < (D) < (C)
D
(B) < (A) < (C) < (D)
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
The reactivity order of carboxylic acid derivatives depends on the leaving tendency of the leaving group. Higher the leaving tendency of the leaving group, higher will be the reactivity of the compound. Therefore, reactivity order towards LiAlH4 is Acid halide > Acid anhydride > Ester > Amide
