Guys this is science. 4.18 Module Exam. I HATE tests! I know it's to test how smart I am but I'm being sarcastic, I AM SMART AND I KNOW IT LOL but I STILL have to take the test! And I don't understand some questions on tests. I'm like yikes sometimes when I get a 60% but its mostly A's and B's. If you support and comfort me on the exact rate, I'll mark you brainliest but I'll wait till I get 2 or more answers and see which one is better! Thanks!

I understand you. I also hate tests. It is ok if you don't understand some questions. That happens to me also. I am also smart but I hate that we still have to take tests! It is so annoying I hope the test goes great though!Have a good day! :)

Explanation:

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.
