Question

Explain the following:

Alkyl halides are insoluble in water though they contain a polar $C-X$ bond.

Answer 1

$\begin{array}{c}\text{Water is polar and alkyl halide is also polar}\text{therefore, like should dissolve like.}\\ \text{But alkyl halide is insoluble in water because}\text{Water forms H-bonding between Water - water molecule}\\ (H_{2}O-H_{2}O)\text{Which is strong interaction.}\text{When Alkyl halide is added to Water Interaction between}\\ \text{Alkyl thalide and water is weaker than inter molecular H-bonding}\\ \text{in water. Alkyl halide is neither able to from}\text{H - bond with water molecule Nor it is able}\\ \text{to break H-bonding between water. That's why Alkyl halides are Insoluble in water.}\end{array}$
