Nomenclature

Question 1

Procedure for naming Carboxylic Acids

Answer 1

1) Find longest continuous carbon chain containing the carboxylic acid group.
2) The carboxyl counts are a carbon atom
3) The carboxylate carbon atom is always number 1
4) -oic/ic acid at the end

Question 2

Procedure for naming Esters

Answer 2

Esters are derivatives of carboxylic acids and alcohols:

1) First, name the alcohol part of the molecule
2) Name the acid part

Question 3

What is the priority of carboxylic acids in naming?

Answer 3

They have the absolute top priority.

Question 4

Procedure for naming Amides

Answer 4

1) The name of an amide is derived from the acid by replacing the ‘-oic acid‘ or ‘-ic acid‘ ending with “amide”, or replacing the -carboxylic acid ending with carboxamide

OR

2) The suffix amide is appended to the name of the hydrocarbon corresponding to the carbon chain that includes the carbonyl group

Question 5

When is ortho/meta/para naming used?

Answer 5

It is used only when there are two substituends on a benzene ring (no less, no more)

Question 6

(Z)/(E)

Answer 6

(Z) is on same side

(E) is on opposite side

Question 7

What functional groups does a peptide bond contain?

Answer 7

amide
