Chapter 3.4, Problem 8LTS

Interpretation Introduction

Interpretation:

For given compound more acidic proton to be identified.

Concept Introduction

Orbital hybridization related to acidity:

The acidity of the proton identified by many factors. One of the factors is hybridization. The negative charge in a ${\text{sp}}^{\text{3}}$-hybridized orbital is more acidic than the negative charge in a ${\text{sp}}^2$-hybridized orbital. Because ${\text{sp}}^2$ hybridized orbital is closer to the nucleus than ${\text{sp}}^{\text{3}}$-hybridized orbital and therefore greater stabilizes a negative charge.
