Chapter 7, Problem 7.50P

(a)

Interpretation Introduction

Interpretation:

The Lewis formula of SF2 has to be written.

Concept Introduction:

Lewis Structure:  A Lewis structure shows a covalent bond as pair of electrons shared between two atoms.

Procedure to write Lewis formulas:

  1. 1) The symbols of the atoms that are bonded together in the molecule next to one another are arranged.
  2. 2) The total number of valence electrons in the molecule is calculated by adding the number of valence electrons for all the atoms in the molecules.  If the species is an ion, then the charge of ion into account by adding electrons, if it is a negative ion or subtracting electrons if it is a positive ion.
  3. 3) A two-electron covalent bond is represented by placing a line between the atoms, which are assumed to be bonded to each other.
  4. 4) The remaining valence electrons as lone pairs about each atom are arranged so that the octet rule is satisfied for each other.

Formal charge (F.C):  The charges that assigned to each atom in a molecule or ion by a set of arbitrary rules and don not actually represent the actual charges on the atoms are called as formal charges.

The formal charge is calculated using the formula,

  F.C=Valenceelectrons-Noofnon-bondingelectrons-Noofbondingelectrons2

The Lewis structure with zero formal charge or least separated formal charges is the preferred structure of the molecule.
