Chapter 19, Problem 22E

Interpretation Introduction

(a)

Interpretation:

The molecular formula for the alkene ${\text{C}}_{\text{8}}{\text{H}}_{\text{?}}$ is to be stated.

Concept introduction:

The molecular formula gives the actual number of atoms of the elements present in the compound. The general molecular formula of the alkene is ${\text{C}}_{\text{n}}{\text{H}}_{\text{2n}}$. Whereas the empirical formula of a compound gives the proportions of the elements present in the compound. The empirical formula does not give the actual number of atoms of the elements present in the compound.
