Answer 1

IUPAC name of \[\begin{array}{cc}
\phantom{}\ce{CH3}\phantom{..........}\ce{Br}\phantom{........}\\
\phantom{}|\phantom{................}|\phantom{.........}\\
\phantom{}\ce{CH3CHCH2CHCHCH2CH3}\phantom{}\\
\phantom{}|\phantom{..}\\
\phantom{..}\ce{CH3}\phantom{}
\end{array}\] is 5-Bromo 2,4-dimethyl heptane.

Explanation:

\[\begin{array}{cc}
\phantom{}\ce{CH3}\phantom{..........}\ce{Br}\phantom{........}\\
\phantom{.}|\phantom{................}|\phantom{..........}\\
\phantom{}\ce{\underset{1}{C}H3\underset{2}{C}H\underset{3}{C}H2\underset{4}{C}H\underset{5}{C}H\underset{6}{C}H2\underset{7}{C}H3}\phantom{}\\
\phantom{}|\phantom{..}\\
\phantom{..}\ce{CH3}\phantom{}
\end{array}\]
