# rite a Lewis structure for each of the following simple molecules. Show all bonding valence electron pairs as lines and all nonbonding valence electron pairs as dots.msp;  a .  GeH 4 c .  NI 3 b .  ICl         d .  PF 3

Interpretation Introduction

(a)

Interpretation:

The Lewis structure for the given molecule is to be drawn. All bonding valence electron pairs are to be shown as lines and all nonbonding valence electron pairs are to be shown as dots.

Concept Introduction:

The representation an element along with its valence electrons is referred to as Lewis symbol or Electron Dot Symbol. The Lewis structure exhibits the connection between atoms. Each dot around an atom represents electrons.

The geometry of the molecule is determined by the electron pairs present around the central atom.

The formula to calculate the number of electron pairs in compound is,

Electronpair=bondpair+lonepair

If electron pairs are 2 then shape of the molecule will be linear.

Similarly, if electron pairs are 3, then shape of the molecule will be trigonal planar.

Explanation

The given molecule is GeH4.

The number of valence electrons in Ge and H is 4 and 1 respectively. Thus, the Lewis structure for GeH4 showing all bonding valence electron pairs as lines is,
