Convert each of the measurements given to the new unit stated using the factor label method (dimensional analysis). Show all work including rewriting the given. Two step conversions:

26 cm to ft. _
16 lb to g _
1 yr to s _
3.5 mi to km _

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.
