352 mL of chlorine under a pressure
of 680. mm Hg are placed in a
container under a pressure of 1210
mm Hg. The temperature remains
constant at 296 K. What is the new
volume of the container? *

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.
