Chapter 4, Problem 101CWP

Interpretation Introduction

Interpretation: The formulas of certain chemical substances have been given. Their compound names and molecular structures are to be stated.

Concept introduction: While naming a covalent compound, the first element is named first followed by the naming of the second element. If the first element exhibits more than one oxidation state then the current oxidation state being exhibited is to be mentioned.

The following steps are to be followed to determine the molecular structure of a given compound,

• The central atom is identified.
• Its valence electrons are determined.
• $1{\text{e}}^{-}$ is added to the total number of valence electrons for each monovalent atom present.
• The total number obtained is divided by $2$, to find the number of electron pairs.

  This further gives us the hybridization of the given compound.

To determine: The name and the structure of the compound having formula ${\text{CO}}_2$.
