Answer:

                  (a) Structure of N, N-ethyl methyl amine : In this amine nitrogen atom is hybridized with a lone pair. Its                 shape    is pyramidal not exactly tetrahedral. This is due to the presence of lone pair on nitrogen atom.                                                                 (b) (i) Acetylation reaction: Introduction of acetyl group.                   (ii) Carbyl amine reaction: Formation of isocyanide from amine.              1
