Consider a solution which is 0.10M in NH3 and 0.20M in NH4Cl. Choose ALL of the following that are true. If NaOH is added, the OH- ions react with the NH3. If HCl is added, the H+ ions react with the NH3. If a small amount of NaOH is added, the pH becomes slightly more basic. If NH4NO3 is added, the pH becomes more basic. If a small amount of HCl is added, the pH becomes slightly more basic.

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.
