(a)
Interpretation:
Bonds formed between N and O should be classified as polar covalent or ionic based on the electronegativity of atoms.
Concept Introduction:
The electronegativity of atoms defines the bond characteristics, as the electron distribution of the bond can be predicted by electronegativity. Electronegativity is tendency to pull bond electrons towards an atom. Electronegativity difference between bonded atoms defines the nature of bond as stated in the following table.
Electronegativity difference | Type of bond | Electron distribution in bond. |
0.5 > | Nonpolar | Electrons are equally distributed. |
0.5 -1.9 | Polar covalent | Electrons are unequally distributed between bonded atoms. (more electrons towards more electronegative atom). |
1.9≤ | Ionic | Electron has been donated to the more electronegative atom from less electronegative atom. |
Answer to Problem 64P
The bond between N and O atom is polar covalent.
Explanation of Solution
The electronegativity of N and O atom is 3.0 and 3.5 respectively. The electronegativity difference will be 0.5.
Since,
Electronegativity difference | Type of bond | Electron distribution in bond. |
0.5 > | Nonpolar | Electrons are equally distributed. |
0.5 -1.9 | Polar covalent | Electrons are unequally distributed between bonded atoms. (more electrons towards more electronegative atom). |
1.9 ≤ | Ionic | Electron has been donated to the more electronegative atom from less electronegative atom. |
Thus, the bond will be polar covalent in nature.

Answer to Problem 64P
The bond between O and H atom is polar covalent.
Explanation of Solution
The electronegativity of O and H atom is 3.5 and 2.1 respectively. The electronegativity difference will be 1.4.
Since,
Electronegativity difference | Type of bond | Electron distribution in bond. |
0.5 > | Nonpolar | Electrons are equally distributed. |
0.5 -1.9 | Polar covalent | Electrons are unequally distributed between bonded atoms. (more electrons towards more electronegative atom). |
1.9 ≤ | Ionic | Electron has been donated to the more electronegative atom from less electronegative atom. |
