An organic compound X having molecular formula C_(3)H_(11) N reacts with p-toluene sulphonyl chloride to form acompound Y that is soluble in aqueous KOH. Compound X is optically active and reacts with acetyl chloride to form compound Z . Identify the compound Z

Answer»

`CH_(3)CH_(2)CH_(2)CH_(2)NHCOCH_(3)`
`CH_(3)CH_(2) overset(CH_(3))overset(|)(C)HNHCOCH_(3)`
`CH_(3)overset(CH_(3))overset(|)(C)HCH_(2)NHCOCH_(3)`
`CH_(3)- underset(CH_(3))underset(|)overset(CH_(3))overset(|)(C)-NHCOCH_(3)`

Solution :Since ,` X [C_(4) H_(11) N]` reacts with p-toluene sulphonyl chloride (Hinsberg reagent ) to form a compound which is soluble in KOH , therefore X MUST be a primary amine
