Chapter 20, Problem 72E

Interpretation Introduction

Interpretation: The molecular structures (including bond angles) for the predicted ${\text{RnF}}_x$ compounds in exercise $71$ are to be stated.

Concept introduction: 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.
• The value $1{\text{e}}^{-}$ 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 the hybridization of the given compound.

To determine: The molecular structures (including bond angles) for the predicted ${\text{RnF}}_x$ compounds in exercise $71$.
