Chapter U2.8, Problem 5E

Interpretation Introduction

(a)

Interpretation:

Molecular formula of given esters is to be written.

Concept introduction:

From the given structural formula, one can write the molecular formula by counting the number of atoms of each element in the molecule and writing the numbers as a subscript to the symbols of elements.

Answer to Problem 5E

The molecular formula of the given ester is C₈H₁₆O₂.

Explanation of Solution

The chemical formula of a compound is also called the molecular formula. It describes the formation of the molecule.

Number of carbon atoms = 8

Number of hydrogen atoms = 16

Number of oxygen atoms = 2

Hence molecular formula is C₈H₁₆O₂.

Interpretation Introduction

(b)

Interpretation:

Molecular formula of given ester is to be written.

Concept introduction:

From the given structural formula, one can write the molecular formula by counting the number of atoms of each element in the molecule and writing the numbers as a subscript to the symbols of elements.

Answer to Problem 5E

The molecular formula of given ester is ${\text{C}}_{\text{7}}{\text{H}}_{\text{14}}{\text{O}}_{\text{2}}$

Explanation of Solution

The chemical formula of a compound is also called the molecular formula. It describes the formation of the molecule.

Number of carbon atoms = 7

Number of hydrogen atoms = 14

Number of oxygen atoms = 2

Hence molecular formula is ${\text{C}}_{\text{7}}{\text{H}}_{\text{14}}{\text{O}}_{\text{2}}$.

Interpretation Introduction

(c)

Interpretation:

Molecular formula of the given ester is to be written.

Concept introduction:

From the given structural formula, one can write the molecular formula by counting the number of atoms of each element in the molecule and writing the numbers as a subscript to the symbols of elements.

Answer to Problem 5E

The molecular formula of the given ester is ${\text{C}}_9{\text{H}}_{\text{18}}{\text{O}}_{\text{2}}$

Explanation of Solution

The chemical formula of a compound is also called the molecular formula. It describes the formation of the molecule.

Number of carbon atoms = 9

Number of hydrogen atoms = 18

Number of oxygen atoms = 2

Hence, the molecular formula is ${\text{C}}_9{\text{H}}_{\text{18}}{\text{O}}_{\text{2}}$

Interpretation Introduction

(d)

Interpretation:

Molecular formula of the given ester is to be written.

Concept introduction:

From the given structural formula, one can write the molecular formula by counting the number of atoms of each element in the molecule and writing the numbers as a subscript to the symbols of elements.

Answer to Problem 5E

The molecular formula of the given ester is ${\text{C}}_6{\text{H}}_{\text{12}}{\text{O}}_{\text{2}}$

Explanation of Solution

The chemical formula of a compound is also called the molecular formula. It describes the formation of the molecule.

Number of carbon atoms = 6

Number of hydrogen atoms = 12

Number of oxygen atoms = 2

Hence, molecular formula is ${\text{C}}_6{\text{H}}_{\text{12}}{\text{O}}_{\text{2}}$
