Drug preparation

Question 9

Esters are formed by

Answer 9

Condensation reaction between an alcohol and a carboxylic acid

Question 10

What happens in a condensation reaction?

Answer 10

The alcohol and carboxylic acid molecules join together by the reaction of their functional groups to make water

Question 11

How is an ester link formed

Answer 11

By the reaction of the hydroxyl group with a carboxyl group

Question 12

Compare straight chain alkane to straight chain alcohol with the same number of carbon atoms

Answer 12

Alcohol has a higher boiling point than alkanes

Question 13

Compare alcohol isomers with -OH on carbon 1 and -OH on Carbon 2

Answer 13

Alcohol with -OH group on the 1st carbon has a higher boiling point

Question 14

Are alcohols soluble in water?

Answer 14

Yes

As the number of carbon atoms in alcohol increases, the solubility if the alcohol in water decreases

Answer 15

Alcoholic drinks 
Solvents 
Fuel 
Car de icers and thermometers 
Feedstock eg vinegar
