Question

Why is the solubility of haloalkanes in water is very low although they are polar in nature?

Answer 1

Hint:A compound consisting of alkanes attached with one or more halogens is known as halo alkanes. Halo alkanes breaks up in natural solvents yet dissolvability in water is pretty low. Solubility relies on the intermolecular forces of attraction.

Complete answer:
Haloalkanes are polar compounds. Water is also a polar compound. As indicated by "like breaks up like'' appropriately, corona alkanes should disintegrate in water. In any case, the dissolvability of corona alkanes show a distinction, they have low solvency in water. The explanation behind similar lies in the energy and intermolecular attractions. For dissolving haloalkanes in water, we first need to break bonds between haloalkane atoms held together by Vander dividers powers and dipole-dipole interactions. The hydrogen obligations of water likewise should be broken. Both these bond breakages require a high measure of energy. Yet, when connections among haloalkanes and water particles are framed, it prompts the arrival of energy. The delivered energy is lower than the energy needed to break the bond. Therefore, that energy cannot be overcome by newly formed dispersion forces and dipole-dipole bonds between haloalkanes and water. Hence, the solubility of haloalkanes for energetics and thus, they are having low solubility in water.

Note: When haloalkanes are dissolved in organic solvent, the energy of bond breakage and the delivered energy after connection of haloalkanes with natural dissolvable is nearly the equivalent. Accordingly, they disintegrate pretty high in natural solvents, for example, benzene.
