Question

PLZ HELP 20 POINTS WILL GIVE BRAINLIEST how does substituting a hydrogen atom with a halogen in a hydrocarbon affect the resulting compound? A. All the single bonds in the original molecule change to double bonds. B. The boiling point of the new compound increases. C. The bonds between the carbon atoms in the molecule becomes weaker. D. The resulting compound is called a saturated hydrocarbon. E. The substitution allows each carbon atom to accept more than four valence electrons.

Answer 1

Organic compounds that contain only hydrogens and carbons are known as hydrocarbons. Hydrocarbons can be saturated or unsaturated in nature. Saturated hydrocarbons are those which contain only carbon-carbon single bonds whereas unsaturated hydrocarbons contain carbon-carbon double or triple bonds. Hydrocarbons can undergo several reactions like substitution, elimination etc.

When one or more hydrogen atoms in hydrocarbon are substituted with halogen it results in the formation of haloalkane. Due to which the molecular weight increases as the halogen atoms are large compared to the carbon and hydrogen atoms. The bond becomes polar due to the presence of electronegative halogen atom and thus results in the increase in boiling point of the haloalkane.

Thus, the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
