Concept explainers
(a)
Interpretation:
The functional group that is present in A but missing in B should be determined.
Concept Introduction:
(b)
Interpretation:
The new functional group that is present in B should be determined.
Concept Introduction:
Functional groups are the groups of atoms or atoms which are bonded with parent carbon chain in the organic molecule and are responsible for the physical and chemical properties of the compound. In organic chemistry, there are different functional groups such as carboxylic acid, alcohol, ester, or amide.
