Chapter 17.2, Problem 17.3CIAP

Interpretation Introduction

Interpretation:

The structure of the given compounds has to be examined whether it is acidic, basic or neither.

Concept Introduction:

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

Ester: One $-OR\text{'}$ group is attached to the carbonyl carbon atom of the compound. It is represented as $RCOOR\text{'}$. The hydrogen atom of $-COOH$ is replaced by an alkyl group.

Salicylic acid: It is a benzoic acid with $-OH$ group on the ortho position. It has $-COOH$  and $-OH$ groups.

Acidic properties of acid: The substituents of high electronegativity $\left(-OH\right),\left(-Cl\right)$ and $\left(N{H}_3{}^{+}\right)$ near the carboxylic groups increase the acidity of carboxylic acids.
