B.
Ionic compounds do not conduct electricity.

C.
Ionic compounds dissolved in water conduct electricity.

D.

for points guys

increased stability in the completion of fluorine's outer shell.

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.
