Chapter 1, Problem 26P

(a)

Interpretation Introduction

Interpretation:Thepolarity in the covalent bond of $\text{ClF}$ molecule needs to be determined.

Concept Introduction:On the basis of bonding, all chemical compounds widely classified as ionic and covalent compounds. Ionic compounds are composed of cation and anion which are held together through electrostatic force of attraction.

Covalent compounds are composed by equal sharing of electrons between bonded atoms. They can be further classified as polar and non-polar covalent compounds. The non-polar compounds have same electronegativity of bonded atoms whereas polar covalent are composed of those bonded atoms which have significant difference in their electronegativity.

Interpretation Introduction

Interpretation:The polarity in the covalent bond of $\text{BrCN}$ molecule needs to be determined.

Concept Introduction: Lewis dot structure is also known as Lewis dot formula or electron dot structure. The bond formation between the atoms takes place due to the sharing of valence electrons of bonded atoms while the remaining electrons present in outer shell represented as lone pair of electrons.

To draw the Lewis structure, calculate the total number of valence electrons in each atom and draw the structure in such a way that each atom gets its octet configuration.
