Chapter 3, Problem 3.106SP

Interpretation Introduction

(a)

Interpretation:

Empirical formula of benzene needs to be determined.

Concept introduction:

The simplest positive integer ratio of atoms of the chemical compound is called an empirical formula. From the empirical formula, the actual number of atoms present in the compound cannot be determined.

Interpretation Introduction

(b)

Interpretation:

Molecular weight and its molecular formula from the mass spectrum of benzene needs to be determined.

Concept introduction:

The chemical symbol is used for constituent elements which are followed by the subscript describing the present number of atoms of each element in the molecule by using the molecular formula.

The value of empirical and molecular formula may be the same or a multiple of the compound empirical formula.
