Which of the following is the weakest of the intermolecular forces? A. Hydrogen bonds
B. Dipole-dipole interactions
C. Dipole-hydrogen interactions
D. London dispersion force

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

you gotta add the following molecules so we can give u an answer

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.
