Question

a covalent bond is likely to be polar when . question 4 options: the two atoms sharing electrons are of the same elements carbon is one of the two atoms sharing electrons one of the atoms sharing electrons is more electronegative than the other atom the two atoms sharing electrons are equally electronegative

Answer 1

A covalent bond is likely to be polar when one of the atoms sharing electrons is more electronegative than the other atom.

When the electronegativity difference is greater, the bond polarity is increasing.

Electronegativity (χ) is a property that describes the tendency of an atom to attract a shared pair of electrons.

Atoms with higher electronegativity attracts more electrons towards it, electrons are closer to that atom.

For example, water (H₂O) is a polar molecule. Atom of oxygen has higher electronegativity and negative charge, while atom of hydrogen has lower electronegativity and positive charge. Atoms of hydrogen and oxygen are connected by polar covalent bonds.
