The correct option is C They dissolve easily in organic solvents.
Alkyl halides are not associated with each other by H-bonds. Hydrogen bonding is possible only if H atom is attached to electronegative N, O or F atom. This is not true in case of alkyl halides. C-halogen bond is polar because of electronegativity difference between carbon and halogen. Alkyl halides dissolve easily in organic solvents. They do not dissolve in water quickly.
