Haloalkanes are insoluble in water. Give reason.

Solution

Haloalkanes (R—X) are insoluble in water because the alkyl group R—(C_nH_2n+1 ,) is hydro-phobic. That is, R group is water repelling. Thus, haloalkanes are unable to form hydrogen bond with water molecules. In other words we may state that haloalkanes cannot break the strong H—bonds existing between H₂O molecules, so R—X molecules do not interact with H₂O molecules and therefore R—X is insoluble in H₂O.
