Answer 1

-OH

Question 2

What are alcohols also known as?

Answer 2

alkanols
- They are a homologous series

Question 3

What is alcohols general formula

Answer 3

CnH2n+1OH

Question 4

Naming alcohols

Answer 4

The rules for naming an alcohol are the same as before. The hydroxyl functional group is the most important part of the molecule and the carbon chain is numbered to give it the lowest branch number.
And they all end in -Ol

Question 5

An example of naming alcohols

Answer 5

CH3CH2CH(OH)CH3
= Butan-2-ol

Question 6

Answer 6

• Intoxicating effects (Drinking)
• Fuels
• Solvents
  -Hand gels/ disinfectant wipes (propan-2-ol)

Question 7

What are the mp/bp for alcohol?

Answer 7

• The melting points and boiling points of alcohols increase with size due to stronger intermolicular forces

Question 8

What is the general formula for Carboxylic acids?

Answer 8

CnH2n+1COOH

Question 9

What are the naming rules for carboxylic acids?

Answer 9

When naming carboxylic acids, the position of the carboxyl group does not need to be identified with a number, as it is always found at the end of the carbon chain, and so is on the first carbon. And they end in - oic

Question 10

What are the melting points and boiling points of carboxylic acids?

Answer 10

The melting points and boiling points of carboxylic acids increases with size due to stronger intermolicular forces

Question 11

What are some uses for carboxylic acids?

Answer 11

• Vinegar ( ethanoic acid) which can also be used for cleaning

Question 12

What are some common salts which are made with carboxylic acids?

Answer 12

Sodium hydroxide+ ethanoic acid =sodium ethanoate +water

Lithium carbonate +propanoic acid =lithium propanoate +water +carbon dioxide
