Space vehicles use solid lithium hydroxide to remove exhaled carbon dioxide according to this equation: 2LiOH CO2 Li2CO3 H2O. Determine the mass of carbon dioxide removed if the space vehicle carries 42.0 mol LiOH. 924g Co2 Some of the sulfur dioxide released into the atmosphere is converted to sulfuric acid according to this equation: 2SO2 2H2O O2 2H2SO4. Determine the mass of sulfuric acid formed from 3.20 moles of sulfur dioxide. Phosphorus burns in air to produce a phosphorus oxide in this reaction: 4P 5O2 P4O10 If 0.489 mol of P is used what mass of P4O10 is produced

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.
