Chapter 3.7, Problem 3.21P

(a)

Interpretation Introduction

Interpretation:

The number of covalent bonds formed by fluorine atom has to be predicted.

Concept Introduction:

Atoms that consist of one, two or three outermost electrons forms one, two or three bonds respectively.

Atoms with four or more outermost electrons form sufficient bonds to form an octet.

  $\text{Predicted}\text{number}\text{of}\text{bonds=8-number}\text{of}\text{valence}\text{electrons}$
