(ii) \[\begin{array}{cc}
\ce{CH3 - CH2 - CH - CH3}\\
\phantom{.....}|\\
\phantom{........}\ce{\underset{(2-nitro butane)}{NO2}}
\end{array}\]

(iii) \[\begin{array}{cc}
\ce{CH3}\phantom{......}\\
|\phantom{.........}\\
\ce{\underset{(2-methyl-1-nitro propane)}{CH3 - CH - CH2 - NO2}}
\end{array}\]

(iv) \[\begin{array}{cc}
\phantom{...}\ce{CH3}\\
|\\
\ce{CH3 - C - NO2}\\
|\\
\phantom{....}\ce{\underset{(2-methyl-2-nitro propane)}{CH3}}
