Chapter 3, Problem 117SAE

Interpretation Introduction

(a)

Interpretation:

To explain the molecular mass and molar mass.

Concept introduction:

Molar mass of an atomic substance is numerically equal to its atomic mass in amu.

$\text{Molar mass of an atom / g = (Atomic mass) / amu}$

Interpretation Introduction

(b)

Interpretation:

To explain the empirical formula and molecular formula.

Concept introduction:

A formula that gives the simplest whole number ratio of the different atoms in a compound is called empirical formula.

A formula which shows the actual number of atoms in a compound is called molecular formula.T

Interpretation Introduction

(c)

Interpretation:

To explain the systematic and trivial or common name.

Concept introduction:

Nomenclature means the assignment of names to the organic compounds. The naming of organic compounds is an important aspect in the study of organic chemistry as their number is vary large and variety of molecular structure exist in their molecules.

Interpretation Introduction

(d)

Interpretation:

To explain the hydroxy and carboxyl functional groups.

Concept introduction:

Functional group of compound has specific characteristic.
