Question
Name the factors responsible for the solubility of alcohols in water.
Advertisements
Solution
Alcohols are soluble in water because of hydrogen bonding with water molecules.
\[\begin{array}{cc}
\phantom{}\ce{R - O - H ⋅⋅⋅ O - H ⋅⋅⋅ O - H ⋅⋅⋅ }\phantom{}\\
\phantom{.......}|\phantom{..........}|\phantom{.}\\
\phantom{.......}\ce{H}\phantom{.........}\ce{R}\phantom{.}
\end{array}\]
The solubility decreases with increase in size of alkyl or aryl group.
