of the following derivatives of

the carboxylic acids:

a. Ethyl 2-hydroxypropanoate

b. Butyl 3,3-dimethyhexanoate

c. N-Ethyl-N-methylbenzamide

d. 2,3-Dibromohexanamide

Explanation:

a.  Ethyl 2-hydroxypropanoate

indicates that the given molecule has -oate suffix that means it has an ester(R-COO-R') functional group.

Prop- indicates that the main carbon chain has three carbon atoms.

Ethyl group at the second position is the substituent.

b. In this molecule has also -oate functional group which means it has an ester functional group.

The rootword hex-indicates that the main carbon chain has six carbons.

Butyl-3,3-dimethyl group is the substituent.

c. N-ethyl-N-methylbenzamide

In this molecule, the aimde group indicates the presence of -CONH2 group.

N-methyl group prefix indicates that the methyl group is attached to N-atom.

N-ethyl prefix indicates the presence of ethyl group to N-atom.

d. 2,3-dibromohexanamide indicates the presence of amide functional group and two bromo groups as substituents at the second and third carbons.

The structures of all the compounds are shown below:

The structures of all the acid derivatives are attached below.

Explanation:

Some of the acid derivatives are:

To name a compound, first look for the longest possible carbon chain.

Amide group is a type of functional group where an amine group is attached to a carbonyl group. The general formula of amide is , where R is an alkyl or aryl group.

Esters are a kind of organic molecules having functional groups, where R and R' are the alkyl or aryl groups. They are formed by the combination of alcohol and carboxylic acid.

These functional group compounds are named in two words which is alkyl alkanoates, where alkyl refers to the alcoholic part and alkanoate refers to the carboxylic acid part of the molecule. The numbering of the parent chain in esters is done from the carboxylic carbon. The alkyl part is not given any numbers.

For (a): Ethyl 2-hydroxypropanoate

The longest possible carbon chain has 3 carbon atoms and prefix used will be 'prop-'.

A hydroxy (-OH) group is attached to the 2nd position.

The structure is attached in the image below.

For (b): Butyl 3,3-dimethyhexanoate

The longest possible carbon chain has 6 carbon atoms and prefix used will be 'hex-'.

2 methyl groups are attached at the 3rd position

The structure is attached in the image below.

For (c): N-Ethyl-N-methylbenzamide

The longest possible carbon chain is a benzene ring

1 methyl and 1 ethyl groups are attached directly to the N-atom

The structure is attached in the image below.

For (d): 2,3-Dibromohexanamide

The longest possible carbon chain has 6 carbon atoms and prefix used will be 'hex-'.

2 bromo groups are attached at the 2nd and 3rd position

The structure is attached in the image below.
