Dipol-dipole Interactions are a type of intermolecular force. They are caused by polar bonds found within nonpolar molecules. When one side of a molecule has an atom that is much more electronegative than the other atoms in the molecule, the atom with the higher electronegativity pulls the electrons more closely to itself causing that end of the molecule to be
partially negative and the opposite end of the molecule to be partially positive. The oppositely charged ends of neighboring molecules attract to one another and this attraction is the

the answer is d. 74.02

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.

answer: cellular respiration takes in food and uses it to create atp, a chemical which the cell uses for energy. usually, this process uses oxygen, and is called aerobic respiration. it has four stages known as glycolysis, link reaction, the krebs cycle, and the electron transport chain.
