The correct IUPAC name of the following alkane is:

\[\begin{array}{cc}
\ce{H3C - CH2 - CH - CH2 - CH2 - CH - CH2 - CH3}\\
\phantom{}|\phantom{...................}|\phantom{..}\\
\phantom{..}\ce{CH}\phantom{................}\ce{CH2}\phantom{.}\\
\phantom{.}/\phantom{.}\backslash\phantom{..................}|\phantom{....}\\
\phantom{}\ce{CH3}\phantom{.}\ce{CH3}\phantom{.............}\ce{CH3}\phantom{..}
\end{array}\]

Options

• 3, 6 – Diethyl – 2 – methyloctane

• 5 – Isopropyl – 3 – ethyloctane

• 3 – Ethyl – 5 – isopropyloctane

• 3 – Isopropyl – 6 – ethyloctane

Answer 1

3, 6 – Diethyl – 2 – methyloctane

Explanation:

\[\begin{array}{cc}
\phantom{}\ce{H3C - CH2 - \overset{3}{C}H - \overset{4}{C}H2 - \overset{5}{C}H2 - \overset{6}{C}H - \overset{7}{C}H2 - \overset{8}{C}H3}\phantom{.}\\
\phantom{.}|\phantom{...................}|\phantom{...}\\
\phantom{..}\ce{CH3 - \overset{2}{C}H}\phantom{................}\ce{CH2}\phantom{........}\\
\phantom{}|\phantom{...................}|\phantom{..}\\
\ce{\underset{3, 6-Diethyl-2-methyloctane}{\phantom{.}\overset{1}{C}H3\phantom{................}CH3}}\phantom{}
\end{array}\]
