Dr. Flores would like an update on your research about what happened to the lake on Titan. Did the lake on Titan evaporate or freeze? After you clearly state your claim, explain how the evidence connects to the claim to support your argument. Remember to explain what happened at both the macro and molecular scale.

i believe it is c.) 1575 j.

the right answer is c i just did the question.

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.
