Chapter 9, Problem 18Q

Interpretation Introduction

Interpretation:

The functional groups present in given molecule structure have to be identified.

Concept Introduction:

Functional group: They are certain substitutes in the organic molecules which determine the characteristic reactions taking place in it.

There are different types of functional groups and it includes alkane, alcohol, aldehyde, amine, ether, carboxylic acid etc.

The cyclic group of atoms with formula ${\text{C}}_{\text{6}}{\text{H}}_{\text{5}}$ is referred as phenyl group.

Alkenes: Alkenes are one of the important types of hydrocarbon which have at least one carbon-carbon double bond ($\text{C=C}$).

The entity formed as a result of bond formation between oxygen and hydrogen is called hydroxyl group. This is represented by $-OH$.

The functional group carboxylic acid is one which contains one hydroxyl group gets bonded with one carbonyl group that is one $\text{-OH}$ bonded with one $\text{C=O}$.

Carboxylic acid: One $-OH$ group is attached to the carbonyl carbon atom of the compound. It is represented as $RCOOH$

Amines are the derivatives of ammonia $\left(N{H}_3\right)$ with one or more of the hydrogens replaced with a substituent such as an alkyl group.
