Chapter 21, Problem 98IL
Interpretation Introduction

Interpretation: To give the empirical and molecular formula for A and B and draw the Lewis structure for A.

Concept introduction:

The reaction of PCl5 and NH4Cl results in evolution of hydrochloric acid. The mixture has to be heated at a temperature of 145 °C for six hours. The products formed are found to have the same elemental composition but different molar masses.

Empirical formula of a compound is the smallest integer ratio of numbers of each element presented in that compound.

Molecular formula of a compound is integer multiple of empirical formula, the integer is depend upon the mass of empirical formula and the molecular mass of the compound.

Lewis structures are diagrams that represent the chemical bonding of covalently bonded molecules and coordination compounds.

It is also known as Lewis dot structures which represent the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.

Unshared, or lone, electron pairs play an important role in determining the chemical and physical properties of organic compounds. Thus, it is important to know which atoms carry unshared pairs. Use the structural formulas below to determine the number of unshared pairs at each designated atom. Be sure your answers are consistent with the formal charges on the formulas. CH. H₂ fo H2 H The number of unshared pairs at atom a is The number of unshared pairs at atom b is The number of unshared pairs at atom c is HC HC HC CH The number of unshared pairs at atom a is The number of unshared pairs at atom b is The number of unshared pairs at atom c is
