Are benzene, sodium bromide, glucose, and pentane more soluble in octane or water, explain why?

Here's what I get  

Explanation:

Benzene and pentane: more soluble in octane. Both substances are nonpolar, so their molecules can easily intermingle with each other.

Sodium bromide: more soluble in water. The polar water molecules hydrate the ions to form Na⁺(aq) and Cl⁻(aq).

Glucose: more soluble in water. A glucose molecule has six OH groups and these can form hydrogen bonds with the water molecules.

bcde is the incorrect answer it is a

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
