Which of the following compounds on hydrolysis by boiling hydrochloric acid form carboxylic acid ?A. `{:(CH_(3)-CHCH_(2)NO_(2)),(" |"),(" "CH_(3)):}`B. `CH_(3)(CH_(2))_(2)CHNO_(2)`C. `(CH_(3))_(3)CNO_(2)`D. none of these.

Answer» Correct Answer - A
Primary nitrocompounds are hydrolysed by boiling `HCl` to a caroxylic acid and hydroxyl amine.
`{:(CH_(3)-CH-CH_(2)NO_(2)+H_(2)O rarr CH_(3)CHCO_(2)H+NH_(2)OH),(" |"" |"),(" "CH_(3)" "CH_(3)),(" "(1^(@))):}`
`2^(@)` Nitrocompounds give ketone and `N_(2)O`.
`2R_(2)CHNO_(2) overset(HCl)(rarr) 2R_(2)CO+N_(2)O+H_(2)O`
