Solution :`1^(@)` gives `N_(2)` GAS. `2^(@)` gives yellow oily compound. `3^(@)`FORM water soluble SALTS.
`CH_(3)CH_(2)NH_(2) + HNO_(2) rightarrow C_(2)H_(5)OH + N_(2)+ H_(2)O`
`R_(2)NH+ HNO_(2) rightarrow R_(2)N-N=O+H_(2)O`
`(CH_(3)CH_(2))_(3)N+HNO_(2) rightarrow [(CH_(3)CH_(2))_(3) NH]NO_(2)^(-)` soluble in water.
