(a) How primary amine is prepared by Hoffmann bromamide degradation reaction? Write equation.
( b) (i) Write IUPAC name of `CH_(3)CH_(2)NH_(2)`.

Explanation

Iioffmann.s Bromamide reaction : When an acid amide is heated with bromine and potassium hydroxide solution, a primary amine is obtained
`R-COHN_(2)+Br_(2)+4KOH underset to triangle R-NH_(2)+K_(2) Co_(3)+2KBr+2H_(2)O and R=CH_(3)`.
( b ) (i) Ethanamine (ii) `(CH_(3))_(2) NltCH_(3)NH_(2)lt(CH_(3))_(2)NH`.
( c ) `C_(6)H_(5)NII_(2)+NaNo_(2)+2IICI underset to (279-278K) C_(6)H_(5)N_(2)^(+)Cl^(-)+NaCl+2H_(2)O`
