Haloarenes are insoluble in water but soluble in benzene. Explain.

Answer : Water molecules form H-bondTypically, polar molecules dissolve in polar solvents and non-polar molecules dissolve in nonpolar solvents — known as like dissolve like rule. However, haloarenes, though polar, are insoluble in water. The reason being that haloarenes can neither form H-bonds with water nor can they break the H-bonds already existing in water. On the other hand, they are soluble in benzene because of the presence of a large hydrocarbon part in benzene. benzene is a hydrocarbon with 6 carbon atoms
