Chapter 11.7, Problem 11.19P

Interpretation Introduction

Interpretation:

Whether vitamin ${\text{B}}_{\text{3}}$ is water soluble or not is to be determined.

Concept introduction:

Water is a polar solvent. To dissolve in water, the compound must be polar. Polar compound is that compound in which polar bonds are present.The unequal sharing of valence electrons in a bond results in polar bond. Polar bond result when the bond formed between two atoms in which one atom is more electronegative than the other one. One example of polar bond is $\text{H}-\text{Cl}$.

Structure of HCl is as follows:

  

In $\text{H}-\text{Cl}$ , Chlorine is more electronegative than hydrogen.
