Interpretation Introduction

(a)

Interpretation:

Whether the bond in MgI2 is nonpolar covalent, polar covalent, or ionic is to be stated.

Concept introduction:

Electronegativity is defined as the tendency of an atom to attract electrons towards it. Polarized bonds are the result of the electronegativity difference between bonding atoms. If the electronegativity difference is 0, the bond is known as nonpolar covalent bond, if electronegativity difference is between 0 to 2.1, then the bond is known as polar covalent bond and if it is more than 2.1, then the bond is known as ionic bond.

Answer to Problem 4.59E

The bonds in MgI2 are polar covalent bond.

Explanation of Solution

The electronegativity values of Mg atom and I atom are 1.2 and 2.5 respectively as given in Table 4.4. Thus, the electronegativity difference is calculated as given below.

ΔEN=EN(I)EN(Mg)=2.51.2=1.3

The electronegativity difference is between 0 to 2.1. Therefore, MgI2 has a polar covalent bond.

Conclusion

The bonds in MgI2 are polar covalent bond.

(b)

Interpretation:

Whether the bond in NCl3 is nonpolar covalent, polar covalent, or ionic is to be stated.

Concept introduction:

Electronegativity is defined as the tendency of an atom to attract electrons towards it. Polarized bonds are the result of the electronegativity difference between bonding atoms. If the electronegativity difference is 0, the bond is known as nonpolar covalent bond, if electronegativity difference is between 0 to 2.1, then the bond is known as polar covalent bond and if it is more than 2.1, then the bond is known as ionic bond.

Answer to Problem 4.59E

The bonds in NCl3 are nonpolar covalent bond.

Explanation of Solution

The electronegativity values of N atom and Cl atom is 3.0 as given in Table 4.4. Thus, the electronegativity difference is calculated as given below.

ΔEN=EN(Cl)EN(N)=3.03.0=0

The electronegativity difference is 0. Therefore, NCl3 has nonpolar covalent bond.

Conclusion

The bonds in NCl3 are nonpolar covalent bond.

(c)

Interpretation:

Whether the bond in H2S is nonpolar covalent, polar covalent, or ionic is to be stated.

Concept introduction:

Electronegativity is defined as the tendency of an atom to attract electrons towards it. Polarized bonds are the result of the electronegativity difference between bonding atoms. If the electronegativity difference is 0, the bond is known as nonpolar covalent bond, if electronegativity difference is between 0 to 2.1, then the bond is known as polar covalent bond and if it is more than 2.1, then the bond is known as ionic bond.

Answer to Problem 4.59E

The bonds in H2S are polar covalent bond.

Explanation of Solution

The electronegativity values of H atom and S atom are 2.1 and 2.5 respectively as given in Table 4.4. Thus, the electronegativity difference is calculated as given below.

ΔEN=EN(S)EN(H)=2.52.1=0.4

The electronegativity difference is between 0 to 2.1. Therefore, H2S has polar covalent bond.

Conclusion

The bonds in H2S are polar covalent bond.

Interpretation Introduction

(d)

Interpretation:

Whether the bond in RbF is nonpolar covalent, polar covalent, or ionic is to be stated.

Concept introduction:

Electronegativity is defined as the tendency of an atom to attract electrons towards it. Polarized bonds are the result of the electronegativity difference between bonding atoms. If the electronegativity difference is 0, the bond is known as nonpolar covalent bond, if electronegativity difference is between 0 to 2.1, then the bond is known as polar covalent bond and if it is more than 2.1, then the bond is known as ionic bond.

Answer to Problem 4.59E

The bond in RbF is ionic bond.

Explanation of Solution

The electronegativity values of Rb atom and F atom are 0.8 and 4.0 respectively as given in Table 4.4. Thus, the electronegativity difference is calculated as given below.

ΔEN=EN(F)EN(Rb)=4.00.8=3.2

The electronegativity difference is more than 2.1. Therefore, RbF has ionic bond.

Conclusion

The bond in RbF is found to be ionic bond.

Interpretation Introduction

(e)

Interpretation:

Whether the bond in SrO is nonpolar covalent, polar covalent, or ionic is to be stated.

Concept introduction:

Electronegativity is defined as the tendency of an atom to attract electrons towards it. Polarized bonds are the result of the electronegativity difference between bonding atoms. If the electronegativity difference is 0, the bond is known as nonpolar covalent bond, if electronegativity difference is between 0 to 2.1, then the bond is known as polar covalent bond and if it is more than 2.1, then the bond is known as ionic bond.

Answer to Problem 4.59E

The bond in SrO is ionic bond.

Explanation of Solution

The electronegativity values of Sr atom and O atom are 1.0 and 3.5 respectively as given in Table 4.4. Thus, the electronegativity difference is calculated as given below.

ΔEN=EN(O)EN(Sr)=3.51.0=2.5

The electronegativity difference is more than 2.1. Therefore, SrO has ionic bond.

Conclusion

The bond in SrO is ionic bond.
