Consider the following compounds Order of basicity of these compounds in decreasing order is

Options

  1. A4 > 1 > 2 > 3
  2. B1 > 3 > 4 > 2
  3. C2 > 3 > 4 > 1
  4. D1 > 3 > 2 > 4

Correct answer

D. 1 > 3 > 2 > 4

Step-by-step solution

(i) Basicity ∝ 1 Electronegativity of nitrogen (ii) -I group decreases basicity (iii) Delocalisation decreases basicity.
