The correct order of increasing basicity of the given conjugate bases ( R = CH ₃ ) is

Options

  1. ARCO O < HC = C < R < N H ₂
  2. BR < HC C < RCO O < N H ₂
  3. CRCO O < N H ₂ < HC C < R
  4. DRCO O < HC C < N H ₂ < R

Correct answer

D. RCO O < HC C < N H ₂ < R

Step-by-step solution

Correct order of increasing basic strength is R - COO ^ (-) < CH C ^ (-) < NH ₂^ (-) < R ^ (-)
