Unit 5.3

Question 1

This type of molecule has no electronegative charges (it is neutral).

Answer 1

nonpolar molecule

Question 2

This type of molecule has positive and negative charges in specific parts.

Answer 2

polar molecule

Question 3

Dipole-dipole bonds are formed between two ___ molecules.

Answer 3

polar

Question 4

How is a dipole-dipole bond formed?

Answer 4

A dipole-dipole is formed when the a positive part of one molecule is attracted to the negative part of another molecule, and vice versa. This bonds the two molecules together, as the atoms within the same molecules are pulling together, as well as the atoms in different molecules.

Question 5

What elements are able to form hydrogen bonds?

Answer 5

oxygen, fluorine, and nitrogen

Question 6

How are hydrogen bonds formed?

Answer 6

Hydrogen bonds are formed when a positive hydrogen atom from one molecule is attracted to the negative part of another.

Question 7

What causes London dispersion?

Answer 7

London dispersion is caused by electrons temporarily moving to one side of their molecule. This causes a temporary bond to be formed between two molecules.
