## Write Lewis structures for the species in Exercise 99 that involve minimum formal charges.

(a)

Interpretation Introduction

Interpretation: The Lewis structures are to be drawn for the given species in exercise 99 that involves minimum formal charges.

Concept introduction: Lewis structures are the structures which clearly show the bonds and the lone pair of electrons present on each species.

Formal charge is the net charge which is experienced by the individual element present in the molecule.

The net charge experienced by the whole species is the overall formal charge of that species.

To determine: The Lewis structure of the species POCl3 that involves minimum formal charges.

### Explanation of Solution

Explanation

The minimum formal charge on POCl3 is zero.

The outer shell of P,O, and Cl contain 5,6, and 7 electrons respectively.

Total valence electrons in POCl3=32e

The Lewis structures of POCl3 is given as,

Figure 1

Both the structures in figure 1 represent that the molecule POCl3 obeys the octet rule.

The formal charge on the central atom is given by the formula,

Formalcharge=Valenceelectrons(Lonepairsofelectrons+Bondingelectrons2)

Where,

• The valence electrons are the electrons present in outer shell of the element.
• Lone pairs are the unshared pairs of electrons present on the element.
• Bonding electrons are the total number of electrons involve in the bond formation.

The valence electrons in P atom are 5 .

The lone pairs of electrons on P atom are Zero.

The bonding electrons in P atom are 4

Substitute the value of the number of valence electrons, lone pairs of electrons and that of the number of bonding electrons, present in the P atom, to calculate the formal charge on the P atom in the POCl3 molecule
