Homework Answers
a) Ans:
The COOH group is attache to
CH3. There are two carbons so it can be named ethane. The presence
of a carboxylic group gives this a suffix oic acid. So, the name
becomes - Ethanoic acid. Common name: Acetic acid.
b) Ans:
The group on the right side of
ester (carboxylate group) has two sp3- carbons so named as ethyl.
To the left of ester, there are 4 carbons so 'but-' and with ester
group, it becomes 'butanoate'. The carboxylate group is given more
preference for numbering, so another carbonyl carbon gets number
three and the name of the compound becomes ethyl
3-oxobutanoate.
c) Ans:
The carboxylate group is
attached to benzene and hence called benzoate. The CH3 group
attached to benzoate is named as methyl. so name become methyl
benzoate.
d) Ans:
Two ethyl groups are attached
to the nitrogen atom, hence named as 'N,N-diethyl'. The nitrogen is
attached to carbonyl carbon so this is an amide. The amide is
formed of propanoic acid. So, the name becomes 'propionamide'. The
complete name - N,N-diethylpropionamide.
e) Ans:
The total number of carbons on the carbon chain = 3. So, 'prop'. Two carboxylic groups are attache to the terminal of the carbon chain so, the name becomes - propanedioic acid.
