Chapter 19, Problem 19.27P

Interpretation Introduction

Interpretation: The given carboxylic acids are to be arranged in order of increasing acidity.

Concept introduction: The major factors that contribute to the acidic strength are $\text{s}$ character, inductive effect and polarity. The high percentage of $\text{s}$ character increases the acidity. There are two types of inductive effects named as positive or electron releasing and negative or electron withdrawing inductive effect. Positive inductive effect lowers the acidic strength of the compounds, whereas negative inductive effect increases the acidic strength of the compounds.
