(a)
Interpretation : Whether the given molecule N2 is a polar covalent or a nonpolar covalent is to be identified.
Concept Introduction :
A covalent bond is formed when there is sharing of electrons between the atoms to fulfill the noble gas configuration. There are two types of covalent bonds; polar covalent bonds and nonpolar covalent bonds. In a polar molecule the bonded pair of electrons is not shared equally among the atoms. If in a molecule the electronegativity of both the atoms is equal or identical, there is no pulling of electrons and they form nonpolar bond.
(a)
Answer to Problem 4E
N2has nonpolar covalent bond.
Explanation of Solution
If in a molecule the electronegativity of both the atoms is equal or identical, there is no pulling of electrons and they share the electrons equally between them. There is no formation of partial charges and this type of bond is called nonpolar covalent bond. In nitrogen molecule both atoms are same so they have no difference in electronegativity. Hence the bond is nonpolar covalent.
(b)
Interpretation : Whether the given molecule HF is a polar covalent or a nonpolar covalent is to be identified.
Concept Introduction :
A covalent bond is formed when there is sharing of electrons between the atoms to fulfill the octet configuration. There are two types of covalent bonds; polar covalent bonds and nonpolar covalent bonds. In a polar molecule the bonded pair of electrons is not shared equally among the atoms. If in a molecule the electronegativity of both the atoms is equal or identical, there is no pulling of electrons and they form nonpolar bond.
(b)
Answer to Problem 4E
HF has polar covalent bond between hydrogen atom and fluorine atom.
Explanation of Solution
In a polar molecule the bonded pair of electrons is not shared equally among the atoms. In HF molecule, the hydrogen and fluorine atom do not share the bonded pair of electrons equally. Fluorine atom with higher electronegativity attracts more electrons than hydrogen atom with low electronegativity. Fluorine has partial negative charge and hydrogen has positive charge. This results in formation of a polar covalent bond.
(c)
Interpretation : Whether the given molecule F2 is a polar covalent or a nonpolar covalent is to be identified.

Answer to Problem 4E
F2has nonpolar covalent bond between two fluorine atoms.
Explanation of Solution
If in a molecule the electronegativity of both the atoms is equal or identical, there is no pulling of electrons and they share the electrons equally between them. There is no formation of partial charges and this type of bond is called nonpolar covalent bond. In fluorine molecule both atoms are same so they have no difference in electronegativity. Hence the bond is nonpolar covalent.
(d)
Interpretation : Whether the given molecule NO is a polar covalent or a nonpolar covalent is to be identified.
Concept Introduction :
There are two types of covalent bonds; polar covalent bonds and nonpolar covalent bonds. In polar covalent molecule there is partial charge on atoms and in nonpolar covalent molecule ther is no partial charge on atoms.
(d)
Answer to Problem 4E
NO is a polar covalent molecule.
Explanation of Solution
In NO molecule oxygen is more electronegative than nitrogen atom. It pulls the electrons towards itself and so develops a partial negative charge on itself. Nitrogen has a partial positive charge, so the molecule is polar covalent.
(e)
Interpretation : Whether the given molecule FCl is a polar covalent or a nonpolar covalent is to be identified.
Concept Introduction :
A covalent bond is formed when there is sharing of electrons between the atoms to fulfill the octet configuration. There are two types of covalent bonds; polar covalent bonds and nonpolar covalent bonds.
(e)
Answer to Problem 4E
FCl has polar covalent bond.
Explanation of Solution
When two atoms with different electronegativities form a covalent bond with each other, the resultant bond is called polar covalent bond. FCl has polar covalent bond between fluorine and chlorine atom as fluorine is more electronegative than chlorine. So fluorine develops a partial negative charge and chlorine develops a partial positive charge.
