Amines

The correct order of basic strength of methyl-substituted amines in aqueous solution is:

  1. A.(CH3)2NH>CH3NH2>(CH3)3N\mathrm{(CH_3)_2NH > CH_3NH_2 > (CH_3)_3N}✓
  2. B.(CH3)3N>CH3NH2>(CH3)2NH\mathrm{(CH_3)_3N > CH_3NH_2 > (CH_3)_2NH}
  3. C.(CH3)3N>(CH3)2NH>CH3NH2\mathrm{(CH_3)_3N > (CH_3)_2NH > CH_3NH_2}
  4. D.CH3NH2>(CH3)2NH>(CH3)3N\mathrm{CH_3NH_2 > (CH_3)_2NH > (CH_3)_3N}

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
