When you are doing an experiment that will have multiple trials, how do you handle averages? a. do not put each individual trial in the data table, average them and just put the average in the table. b. the individual trials and the averages should each have their own columns in the data table. c. averages do not need to go in the data table, the reader can calculate it if they need to know it. d. averages should never be used, they will cause rounding errors in the data.

the answer would be a

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.
