5. Write the IUPAC name of a) triethylamine b) acetamide 6. a) Write a chemical equation that explains the observations on the heating of benzamide with NaOH b) Write a chemical equation that explains the observations on the addition of HCI to the mixture of benzamide and NaOH subsequent to heating 7. a) Write a chemical equation that explains the observations on the addition of HCI to the mixture of N-methylaniline and water. b) Write a chemical equation that explains the observations on the addition of mixture of N-methylaniline, water, and HCl.

Explanation / Answer

Q5

a)

triethylamine --> has CH3-CH2 groups bonded to a Nitrogen

therefore

this is an amine, therefore "amine"

the lognest chain contains CH3-CH2 and N, then --> ethan-amine ethanamine

all other branches, CH2-CH3 must be stated as "n,n"

N,N --> denotes all other "ethyl" groups are bonded to the Nitrogen

then

N,N-Diethylethanamine

b)

acetamide -->

containes an amide group

acet --> implies CH3-CH2 presence (ethan-)

therefore

Ethanamide
