Answer #1

Part A:

A covalent bond is formed by sharing of electrons by two atoms. In a polar covalent bond, the electron cloud of the shared pair of electrons lie more towards the most electronegative atom among the two. Therefore in a polar covalent bond, the electrons are unequally shared.

Therefore the correct answer is the third option, that is:

A polar covalent bond is a covalent bond in which electrons are shared unequally, being more attracted to one atom than the other

Part A:

Among the given examples, C-Br represents a polar covalent bond, C-C represents a non-polar covalent bond,

Cl-Cl represents a non-polar covalent bond and Na-Cl represents an ionic bond

Therefore the correct answer is the first option, that is:

C-Br

  • A covalent bond is a bond in which electrons are shared between atoms of elements

    A covalent bond is a bond in which electrons are shared between atoms of elements. A covalent bond can be polar or nonpolar. In a nonpolar covalent bond, the bond is between two identical atoms and the electrons are evenly shared between the atoms.In contrast, in a polar covalent bond, the bond is between two nonidentical atoms and the electrons are unevenly shared between the atoms. The uneven sharing of electrons takes place because of the difference in the electronegativity...
