Chapter 4, Problem 4.59SP

(a)

Interpretation Introduction

Interpretation:

Electron-dot structure for given molecule which shows lone pairs has to be drawn and multiple bonds has to be identified.

Concept introduction:

Electron-dot structure:

This is only way to show the sharing of electrons between atom in polar covalent bonds or covalent bond.  This is often called Lewis structure.  This structure denotes valence electrons of an atom by dots and also it shows the way of valence electron distributed within a molecule.
