Why are haloalkanes only slightly soluble in water but readily soluble in organic solvents?

Q: What is the correct answer for CBSE12?

The correct answer is C. To dissolve haloalkanes in water, energy is needed to overcome the attractions between haloalkane molecules and to break the hydrogen bonds between water molecules. The energy released when new attractions are formed between haloalkane and water molecules is not sufficient to compensate for the energy required to break the strong hydrogen bonds in water. However, in organic solvents, the intermole

Q: What are the options for this CBSE12 question?

A. Haloalkanes are non-polar, while water is polar. · B. The energy required to break hydrogen bonds in water is much less than the energy released by new attractions with haloalkanes. · C. New intermolecular attractions between haloalkanes and water are not as strong as the original hydrogen bonds in water. · D. Haloalkanes have very low molecular mass.

Question

Why are haloalkanes only slightly soluble in water but readily soluble in organic solvents?

FirstInTest · Accepted Answer

To dissolve haloalkanes in water, energy is needed to overcome the attractions between haloalkane molecules and to break the hydrogen bonds between water molecules. The energy released when new attractions are formed between haloalkane and water molecules is not sufficient to compensate for the energy required to break the strong hydrogen bonds in water. However, in organic solvents, the intermolecular attractions formed are comparable in strength to those being broken, leading to good solubility.

Answer

Haloalkanes are non-polar, while water is polar.

Answer

The energy required to break hydrogen bonds in water is much less than the energy released by new attractions with haloalkanes.

Answer

New intermolecular attractions between haloalkanes and water are not as strong as the original hydrogen bonds in water.

Answer

Haloalkanes have very low molecular mass.
