Dr. brown's science class is studying changes in particle motion during phase changes by adding a few pieces of dry ice to a flask and covering it with a balloon. after a few minutes they observed the balloon starting to inflate. predict what will happen if they put the flask with the inflated balloon into the freezer.

the balloon put in the freezer will deflate i hope this was helpful if not let me know.

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.
