Although haloalkane are polar in nature, Yet they are slightly soluble in water. Which characteristic behavior is responsible for such kind of property?a)Attraction between halogen and water is less then the attraction between original water moleculesb)Attraction between halogen and water is morethen the attraction between original water moleculesc)Attraction between halogen and water is totally absentd)Attraction between halogen and water is same as the attraction between original water moleculesCorrect answer is option 'A'. Can you explain this answer?

Question

Answer

Haloalkanes aren't very soluble in water because they can't form hydrogen bonds, and the energy required to break hydrogen bonds in water etc is higher than the energy released when new bonds between the haloalkane and water are formed.

Answer

Haloaklanes are polar in nature but still insoluble in water ...this is due to ..they do no dissociate the hydrogen bonding already present among water moluculesthank u

A option

Answer

Explanation:
Haloalkanes are organic compounds that contain at least one halogen atom (chlorine, bromine, iodine, or fluorine) bonded to a carbon atom. They are polar in nature due to the difference in electronegativity between the carbon and halogen atoms. However, despite being polar, haloalkanes are only slightly soluble in water.

Attraction between halogen and water is less than the attraction between original water molecules:
The reason haloalkanes are slightly soluble in water is due to the relatively weak attraction between the halogen atom and water molecules compared to the strong attraction between water molecules themselves. This can be explained by the concept of 'like dissolves like.'

Like dissolves like:
According to this principle, substances with similar polarity or intermolecular forces are likely to dissolve in each other. Water is a polar molecule, meaning it has a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom. This polarity allows water molecules to form hydrogen bonds with each other, resulting in a strong intermolecular attraction.

Intermolecular forces involved:
In the case of haloalkanes, the attraction between the halogen atom and water molecules is primarily dipole-dipole interactions. These interactions are relatively weaker than the hydrogen bonding between water molecules. As a result, the haloalkanes have a higher affinity for their own molecules than for water molecules.

Effect on solubility:
The weak attraction between the halogen and water molecules reduces the solubility of haloalkanes in water. Only a small amount of haloalkane can break the hydrogen bonding network of water and dissolve in it. Additionally, the size of the halogen atom also affects solubility, with larger halogens being less soluble in water.

Conclusion:
In conclusion, the slightly solubility of haloalkanes in water is due to the weaker attraction between the halogen atom and water molecules compared to the strong hydrogen bonding between water molecules themselves. This weaker attraction prevents the haloalkanes from fully dissolving in water and results in their limited solubility.
