PLZ HELP I BEG YOU Short-wave solar radiation gets absorbed by the earth's surface and is reflected back to space as infrared radiation. What happens to the infrared radiation?

Hint: the greenhouse effect

It is absorbed by carbon dioxide and water in the atmosphere.

Nothing, it just sits there.

there is no such thing as infrared radiation because you can see it.

ultraviolet radiation is absorbed

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.
