Account for Reduction of CH_3CN " gives "CH_3CH_2NH_2 while CH_3NC " gives "(CH_3)_2NH. |

Answer» SOLUTION :`CH_3CN` (METHYL cyanide) on REDUCTION gives `CH_3CH_2NH_2` (ethylamine) because addition of hydrogen takes palce at `equiv CN` `{:(CH_3-CequivNunderset(4[H])overset(LiAH_4)(to)CH_3-CH_2NH_2),("Ethylamine (Primary amine) "):}` Whereas `CH_3NC` (Methyl ISOCYANIDE) on reduction with `LiAlH_4` gives secondary amine  In methyl cyanide, -CN group is attached to alkyl group and by reduction it gives a primary amine whereas in methyl isocyanide -NC group is attached to alkyl group and by reduction it gives a secondary amine. |
