Okay so this is a reaction in baking of the decomposition of sodium bicarbonate (baking soda)

So if there is 52.0 grams of sodium bicarbonate, how many liters of carbon dioxide gas would be produced?

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.
