Lesson 5.3

Question 1

What is hydrogen bonding?

Answer 1

Strong dipole-dipole interactions between two molecules that each contain an O-H,N-H,F-H

Question 2

Define dipole-dipole?

Answer 2

Attractive forces between the opposite ends of 2 polar molecules

Question 3

What is london dispersion forces?

Answer 3

Temporary attraction between other atoms and molecules

Question 4

Rank the three types of bonds from strongest to weakest

Answer 4

Strongest - Hydrogen bonding
Mid - Dipole-dipole
Weakest - London Dispersion Forces

Question 5

How do molecules become polar?

Answer 5

Polar molecules must contain a polar covalent bond and asymmetrical ends.

Question 6

What is delta?

Answer 6

The absolute value diffrence

Question 7

What results in a larger partial charge?

Answer 7

A larger electronegativity

Question 8

How can we determine if the molecule is polar or non-polar?

Answer 8

We draw the dipole movements for the molecule to see if they cancel out and then we also observe the forces.

Question 9

How can we determine if a molecule will be soluble in water based on its structure?

Answer 9

By looking at the molecule structure and if the ends are hydrophilic or hydrophobic
