Ch14 Alcohols

Question 1

What are Alcohols?

Answer 1

• Alcohols are homologous series
• General formula C2H2n+1OH
• They are NOT hydorcarbons
• They have a hydroxyl (OH) functional group
• position of OH needs to be indicated by number

Question 2

Answer 2

Question 3

How do alkanes and alcohols compare in terms of intermolecular forces?

Answer 3

Question 4

How do alkanes and alcohols compare in terms of volatility and boiling points?

Answer 4

Question 5

Describe the solubility of alcohols in water.

Answer 5

Question 6

What is 1º, 2º and 3ºclassification of alcohols?

Answer 6

Question 7

What are the 4 reactions that alcohols undergo?

Answer 7

1. Combustion
2. Oxidation
3. Dehydration (alcohol -> alkene)
4. Substitution

Question 8

Describe Combustion of Alcohols:

Answer 8

Question 9

In basic terms, explain the oxidation of alcohols

do not go into 1º or 2º yet

Answer 9

Question 10

Explain the oxidation of 1ºalcohols

Answer 10

Question 11

Explain the oxidation of 2º alcohols

Answer 11

Question 12

Explain the oxidation of 3º alcohols

Answer 12

3ºalcohols do NOT undergo oxidation reactions - colour stays orange
* carbon atom that carries the OH group does not have a hydrogen atom attached but is instead bonded to other carbon atoms

Question 13

Explain the dehydration of alcohols:

Answer 13

Question 14

Explain the Substitution of alcohols
