Question 8

Nanometers is how many?

Answer 8

Nanometers = 10^-9

Question 9

How does hydrogen bonding affect boiling point?

Answer 9

Hydrogen bonding ability will increase the boiling point of a molecule because it is a strong intermolecular force

Question 10

What does a primary alcohol form when oxidized?

Answer 10

A primary alcohol can be oxidized to form an aldehyde or a carboxylic acid

Question 11

What does a secondary alcohol form when oxidized?

Answer 11

A secondary alcohol can be oxidized to form a ketone

Question 12

What does a tertiary alcohol form when oxidized?

Answer 12

Trick question - tertiary alcohols are rarely oxidized because that would require breaking the molecules C-C bonds
