Chapter 3.3, Problem 11ATS

Interpretation Introduction

Interpretation:

For deprotonating hydroquinone, can hydroxide ion acts as strong base has to be identified.

Concept Introduction:

Using $p{K}_a$values to compare Acidity: In general, acid-base reaction said to reach equilibrium; the position of equilibrium is described by the term $K_{eq}$. When an acid-base reaction is carried out in aqueous solution, the new term arrives by the term $K_a$.

$p{K}_a=-log{K}_a$

$p{K}_a$ Values are used as measure of acidity; a strong acid will have a low $p{K}_a$ and a weak acid will have a high $p{K}_a$.

Using $p{K}_a$values to compare Basicity: $p{K}_a$ Values are also used to compare bases; by drawing the conjugate acid of each base and compare the $p{K}_a$ values and identify the stronger base.
