Discuss how viscosity and molecular weight correlated using the data from the CMC experiment. Discuss how the results from both the Brookfield viscometer are used to interpret molecular weight. Describe the relationship between the various terms used in this part of the experiment, including rheology, viscosity, flow, resistance, molecular weight, etc. Be sure to correlate your discussion above specifically to the observations from the viscometer video and cite any sources.

chemistry sucks a**

explanation:

the answer would be c

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.
