Chapter 12, Problem 11A

(a)

Interpretation Introduction

Interpretation:

The more polar bond is to be found out in the given pair of H-O and H-N.

Concept introduction:

A bond is polar if there is difference in electronegativity values of atoms forming the bond.

Electronegativity is denoted by χ

  χAB=χAχBifχA>χBandχBχAifχB>χA

More the difference, more is polarity of bond.

Answer to Problem 11A

  HO is more polar than HN

Explanation of Solution

  χH=2.2χO=3.44χN=3.04

Thus,

χHO=3.442.2=1.24χHN=3.042.2=0.84

Electronegativity difference of HO is more than HN ,therefore HO is more polar than HN

(b)

Interpretation Introduction

Interpretation:

The more polar bond is to be found out in the given pair of H-F and H-N.

Concept introduction:

A bond is polar if there is difference in electronegativity values of atoms forming the bond.

Electronegativity is denoted by χ

  χAB=χAχBifχA>χBandχBχAifχB>χA

More the difference more is polarity of bond.

Answer to Problem 11A

  HF is more polar than HN

Explanation of Solution

  χH=2.2χN=3.04χF=3.98

Thus,

χHN=3.042.2=0.84χHF=3.982.2=1.78

Electronegativity difference of HF is more than HN ,therefore HF is more polar than HN

(c)

(d)

Interpretation Introduction

Interpretation:

The more polar bond is to be found out in the given pair of H-O and H-Cl.

Concept introduction:

A bond is polar if there is difference in electronegativity values of atoms forming the bond.

Electronegativity is denoted by χ

  χAB=χAχBifχA>χBandχBχAifχB>χA

More the difference, more is polarity of bond.

Answer to Problem 11A

  HO is more polar than HCl

Explanation of Solution

  χH=2.2χO=3.44χCl=3.16

Thus,

χHO=3.442.2=1.24χHCl=3.162.2=0.96

Electronegativity difference of HO is more than HCl ,therefore HO is more polar than HCl
