Chapter 6, Problem 45A

(a)

Interpretation Introduction

Interpretation: The element having higher electronegativity is to be determined.

Concept introduction:

An atom's tendency to attract the bonding electrons into a covalent bond is known as electronegativity.

Answer to Problem 45A

F

Explanation of Solution

The electronegativity decreases down the group and increases across the period. Element Cl is placed below F. So, F will have higher electronegativity than Cl.

(b)

Interpretation Introduction

Interpretation: The element having higher electronegativity is to be determined.

Concept introduction:

An atom's tendency to attract the bonding electrons into a covalent bond is known as electronegativity.

Answer to Problem 45A

N

Explanation of Solution

The electronegativity decreases down the group and increases across the period. C is placed in group 14 and N is placed in group 15. So, nitrogen is placed right to the C.

Thus, the electronegativity of N is more than C.

(c)

Interpretation Introduction

Interpretation: The element having higher electronegativity is to be determined.

Concept introduction:

An atom's tendency to attract the bonding electrons into a covalent bond is known as electronegativity.

Answer to Problem 45A

Mg

Explanation of Solution

The electronegativity decreases down the group and increases across the period. Mg is placed below Ne, so Ne should have higher electronegativity than Mg. Since Ne is a noble gas, its electronegativity is zero.

Thus, among Mg and Ne, Mg will have higher electronegativity.

(d)

Interpretation Introduction

Interpretation: The element having higher electronegativity is to be determined.

Concept introduction:

An atom's tendency to attract the bonding electrons into a covalent bond is known as electronegativity.

Answer to Problem 45A

As

Explanation of Solution

The electronegativity decreases down the group and increases across the period. Ca is placed in group 2 and $\text{As}$ is placed in group 15. Since $\text{As}$ is present right to Ca, thus, the electronegativity of $\text{As}$ is more than Ca.
