Among the following  number of amines can be prepared by Gabriel’s pththalimide synthesis are….

(i)  ${\left(C{H}_3\right)}_{2}CHN{H}_2$             (ii)  $H_{3}C-NH-C{H}_{2}C{H}_3$                    (iii)  $C_6{H}_{5}N{H}_2$                   

 (iv) $C_6{H}_5-C{H}_{2}N{H}_2$       (v)  $C{H}_{3}N{H}_2$    (vi)  
(vii)  

Only $1^0$-alphatic amines can be prepared from Gabriel’s phthalilmidesynthesis, where a halogen is replaced by $N{H}_2$ group. In cholrobenzene, Cl is attached to $s{p}^2-$hybridized carbon, hence aniline cannot be prepared while halogen atom in 2,4-dinitrochlorobenzene is replaceable, hence compound (vi) can be prepared.
