Question 14.6: Draw the structure for 3-methoxybutan-2-ol . ANALYSIS First,...

The parent compound is a 4-carbon chain with the —OH attached to C2.

\begin{matrix}\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, OH \\ \overset{4}{C} — \overset{3}{C}— \overset{2|}{C}— \overset{1}{C} \end{matrix}       Butan-2-ol

The 3-methoxy substituent indicates that a methoxy group (— OCH_3) is attached to C3.

\begin{matrix}\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, OH \\ \overset{4}{C} — \overset{3}{\underset{|}{C} }— \overset{2|}{C}— \overset{1}{C} \\\underset{|}{O} \,\,\,\,\,\,\,\,\,\,\,\,\,\\CH_3\,\,\,\,\,\,\end{matrix}      3-Methoxybutan-2-ol
