CHAPTER 5

Question 1

What is an acid?

Answer 1

Molecular compounds that release (H+) cations when dissolved in water

Question 2

What is a base?

Answer 2

Ionic compounds that release (OH-) anions when dissolved in water

Question 3

What is an electrolyte?

Answer 3

Dissolve into ions and conduct electricity

Question 4

What is a non-electrolyte?

Answer 4

Dissolve into ions and DO NOT conduct electricity

Question 5

How do you determine electronegativity from the periodic table?

Answer 5

Electronegativity increases as the periods go up and go right
F = higest
Fr = lowest

Question 6

What is a nonpolar covalent bond in difference in electronegativity?

Answer 6

<0.5

Question 7

What is a polar covalent bond in difference in electronegativity?

Answer 7

0.5-1.7

Question 8

What is a ionic bond in difference in electronegativity?

Answer 8

> 1.7
Usually compounds with elements from group 7 w/ 1 or 2 are usually ionic

Question 9

What is the dispersion force?

Answer 9

The force that acts between all molecules

Question 10

When is the dispersion force stronger?

Answer 10

Between more polarizable/larger molecules

Question 11

What is the dipole force?

Answer 11

A force that acts only between molecules that have a dipole moment (magnitude of polarity)

Question 12

When is the dipole force strongest?

Answer 12

Bigger/more widely spaced charges
