What patterns do you observe in the data?

Explanation:

What type of graph is most appropriate to present the data in Table 4? Create a graph of the data in Excel or another graphing software and submit it to your instructor.

Develop a detailed hypothesis for your experiment.What would your experimental approach be to test this hypothesis? Be detailed in your description of the experiment.

6.What are the independent, dependent, and controlled variables in your experiment?

What type of graph would be appropriate for this data set? Why?

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.
