17.3 1 Carboxylic acids and their physical properties

Question 1

Group

Answer 1

COOH

Question 2

Suffix

Answer 2

-oic acid

Question 3

Bonding

Answer 3

C=O  
3 Polar bonds 
C=O
C-O
O-H

Question 4

Carboxylic scent

Answer 4

very sour taste

unpleasant

Question 5

Boiling temperatures

Answer 5

strong intermolecular forces hydrogen bonding
higher boiling points than other organic compounds
hydrogen bonding
as carbon chain increases the london forces between non-polar hydrocarbon chain increase
boiling point increase with molar mass

Question 6

Shorter chain carboxylic acids

Answer 6

form dimers double molecules in the absence of a solvent hydrogen bonding between two molecules

Question 7

Solubility in water

Answer 7

shorter chains carboxylic acids are soluble in water because they can form hydrogen bonds with water molecules solubilty decreases with chain lengths as the hydrocarbon molecules become larger
