Looking at the map, what ideas do you have about why the trash is "trapped" in this location

Due to the circulation of the wind and water the trash will continue to go around in a circle thus causing it to be trapped there.

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.
