Question

The correct order of acidic and basic strength for the following pair of compounds should be?

• A. (I) < (II)
• B. (III) > (IV)
• C. (V) < (VI)
• D. (VII) > (VIII)

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A (I) < (II)
B (III) > (IV)
C (V) < (VI)
D (VII) > (VIII)



Due to the ortho effect, the acidic strength of ortho substituted benzoic acid increases and the basicity of ortho substituted aniline decreases. The effect does not depend upon the nature of the substituent.
