Chapter 1, Problem 25P

(a)

Interpretation Introduction

Interpretation:TheLewis structure of $\text{ClF}$ molecule needs to be drawn and charges needs to be assigned.

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.

Answer to Problem 25P

  

Explanation of Solution

To draw the Lewis structure, calculate total number of valence electrons. Draw these valence electrons and bonded electrons with atoms in such a way that all bonded atoms get octet configuration.

In $\text{ClF}$ molecule:

Total number of valence electrons = $\text{(7}\times \text{1) }+\text{(7}\times \text{1) = 14}$

  

Both Cl and F have octet configuration so there will be no charge on any atom.
