How many mL of a 3.0M HCl solution do you need to dilute and prepare a 75.0 L of 0.050M solution of HCI? 0.8 x 10^3 mL
O 1.25
ml 1.25 x 10^3 mL
4.5 x 10^3 ml​

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.
