The correct order of decreasing basic strength of the given amines is: Answer (1) Sol. Lower is the value of pKb\mathrm{pK}_{\mathrm{b}}pKb​, higher is the basicity Also aliphatic amines are stronger bases than aromatic amines. pKb\mathrm{pK}_{\mathrm{b}}pKb​ : Benzenamine > N-Methylaniline > Ethanamine > N-Ethylethanamine Basic strength : N-Ethylethanamine > Ethanamine > N-Methylaniline > Benzenamine

  1. A
    N -ethylethanamine > ethanamine > N-methylaniline > benzenamine
  2. B
    benzenamine >>> ethanamine >N>\mathrm{N}>N-methylaniline >N>\mathrm{N}>N-ethylethanamine
  3. C
    N -methylaniline > benzenamine > ethanamine > N-ethylethanamine
  4. D
    N-ethylethanamine > ethanamine > benzenamine > N-methylaniline

Correct answer: A

Lower is the value of $\mathrm{pK}_{\mathrm{b}}$, higher is the basicity

Also aliphatic amines are stronger bases than aromatic amines.

pKb : Benzenamine > N-Methylaniline > Ethanamine > N-Ethylethanamine

Basic strength : N-Ethylethanamine > Ethanamine > N-Methylaniline > Benzenamine
