A student has been given a compound " x " of molecular formula- C ₆ H ₇ ~N . ' x ' is sparingly soluble in water. However, on addition of dilute mineral acid, ' x ' becomes soluble in water. ' x ' when treated with CHCl ₃ and KOH ( alc ) , ' y ' is produced. ' y ' has a specific unpleasant smell. On treatment with benzenesulphonyl chloride, ' x ' gives a compound ' z ' which is soluble in alkali. The number of differ

Step-by-step solution

Compound X has molecular formula C₆H₇N , is sparingly soluble in water but soluble in dilute mineral acid → primary aromatic amine (aniline). X with CHCl ₃ + KOH (alc.) gives Y with unpleasant smell → carbylamine reaction, confirms primary amine. X with benzenesulphonyl chloride gives Z which is soluble in alkali → Hinsberg test confirms primary amine. Z is N-phenylbenzenesulfonamide. Structure of Z: C ₆ H ₅ -NH-SO ₂ -C ₆ H ₅
