What is the initial temperature if a gas at 735 torr occupying a volume of 755 ml is compressed to a pressure of 1.06 atm in 228
mL at 37 °C?

bcde is the incorrect answer it is a

a is the correct answer

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.
