In this balanced reaction, the mole ratio of reactants sulfuryl chloride and 1-chlorobutane is 1: 1. in lab you used approcimately 2x as many moles of chlorobutane as sulfuryl chloride. offer an explanation for the different mole ration of these reactants in your explanation

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
