amines

Question 1

What are amines?

Answer 1

organic derivatives of ammonia in which one or more hydrogen atoms of ammonia has ben replaced by an alkyl group

Question 2

How can amines be classified?

Answer 2

as primary, secondary or tertiary according to the number of alkyl groups attached to the nitrogen atom

Question 3

What to amines react with to form what?

Answer 3

with acids to form salts

Question 4

What types of amines display H bonding? What is the result of this?

Answer 4

primary and secondary but not tertiary. As a result, primary and secondary amines have higher bp points than isometric tertiary amines

Question 5

Which amine molecules can H bonding with water molecules and what does this explain?

Answer 5

primary, secondary and tertiary

This explains the appreciable solubility of the shorter chain length amines in water

Question 6

What are amines like ammonia?

Answer 6

weak bases

They dissociate to a slight extent in aqueous solution.
The nitrogen atoms has a lone pair of electrons which can accept a proton from water, producing hydroxide ions
