Answer» the distinguished of `CHCI_(3),""^(-)OH` the action of `HNO_(2)`, A liberates `N_(2)` gas while B does not the action of `CS_(2), HgCI_(2)`. A gives ODOUR o f mustard oil while B doesn't the TREATMENT of benzene sulphonyl chloride, 'A' gives alkali soluble product Solution :`CH_(3)underset(1^(@) "amine")underset(CH_(3))underset(\|)(CHNH_(2))overset(H_(3)O)(larr)CH_(3)underset(CH_(3))underset(\|)(CHNC)overset(H_(2),Ni)underset("heat")(rarr)CH_(3)underset(2^(@)"amine")underset(CH_(3))underset(\|)(CHNHCH_(3))` `CHCI_(3)OH^(-)` gives a pungent smell with `1^(@)` amine not with `2^(@)` amine . `HNO_(2):1^(@)` amine gives out usually alcohol liberating `N_(2) 2^(@)` amine gives nitroso COMPOUND . `CS_(2)//HgCI_(2):1^(@)"amine"rarrRNH-overset(S)overset(\|\|)(C)-SHoverset(HgCI_(2))(rarr)underset("oil odour")underset("Mustard")(RN=C=S)` `2^(@)"amine"R-underset(R)underset(\|)N-overset(S)overset(\|\|)C-SHoverset(HgCI_(2))(rarr)"no action"` `1_(@)` amine gives alkali soluble sulphonate.
