\section{WM1}
\subsection{Alcohols}
\subsubsection{Physical Properties of Alcohols}
\begin{itemize}
\item Polar due to $O$-$H$ bond
\item Able to hydrogen bond
\begin{itemize}
\item Explains why alcohols have higher MBP's than corresponding alkanes
\item Also explains why alcohol and water mix
\end{itemize}
\item $O$-$H$ bond becomes less influential in longer chains
\begin{itemize}
\item Solubility in water decreases
\item Other properties more similar to those of corresponding alkanes
\end{itemize}
\end{itemize}
\subsection{Reactions of Alcohols}
\subsubsection{Types of alcohols}
\textit{Primary alcohols:}
\begin{itemize}
\item -$O$-$H$ carbon bonded to one other
\end{itemize}
\textiit
\begin{itemize}
\item -$O$-$H$ carbon bonded to two others
\end{itemize}
\textit{Tertiary alcohols:}
\begin{itemize}
\item -$O$-$H$ carbon bonded to three others
\end{itemize}
\subsubsection{Oxidation}
\begin{itemize}
\item The $O$-$H$ group is oxidised by strong oxidising agents
\begin{itemize}
\item Acidified Potassium Dichromate(VI), $K_2Cr_2O_7
\begin{itemize}
\item Orange dichromate ion reduced to green chromate(III) ion
\item $Cr_2O_7^{2-}\Rightarrow Cr^{3+}$
\end{itemize}
\end{itemize}
\item $O$-$H$ group converted to carbonyl $C$=$O$ group
\item Will not take place if there is no hydrogen attached to the carbon
\item Carbonyl formed depends on reacting alcohol and conditions
\begin{itemize}
\item Aldehyde or ketone
\end{itemize}
\end{itemize}
\subsubsection{Heating under Reflux}
\begin{itemize}
\item Safer when using volatile compounds
\begin{itemize}
\item Prevents loss of solvent, reagent, or product
\end{itemize}
\subsubsection{Oxidation of Primary alcohols}
\begin{itemize}
\item Initially oxidised to an Aldehyde
\item Can be further oxidised to a Carboxylic Acid
\begin{itemize}
\item Excess oxidising agent
\iten Under reflux
\end{itemize}
\end{itemize}
\item If the Aldehyde is required:
\begin{itemize}
\item Distilled in situ
\begin{itemize}
\item Prevents further oxidation
\end{itemize}
\item Excess Alcohol
\item No reflux
\end{itemize}
\end{itemize}
