Explain why the energy harnessed per person (per capita) has increased so dramatically since the industrial revolution.

Increased energy use leads to increased economic activity and an increased quality of life. Ever since the industrial revolution, advances in technology have let humans in industrialized nations increase their standard of living significantly, which required significant increases in the amount of energy harnessed per capita.

2b2t

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.
