Detailed explanation-1: -A polar bond is a type of covalent bond. A bond between two or more atoms is polar if the atoms have significantly different electronegativities (>0.4). Polar bonds do not share electrons equally, meaning the negative charge from the electrons is not evenly distributed in the molecule. This causes a dipole moment.
Detailed explanation-2: -A polar covalent bond is a covalent bond in which the atoms have an unequal attraction for electrons and so the sharing is unequal. In a polar covalent bond, sometimes simply called a polar bond, the distribution of electrons around the molecule is no longer symmetrical.
Detailed explanation-3: -A polar bond is a covalent bond in which there is an electronegativity difference between the two bonded atoms and electrons are shared unequally.
Detailed explanation-4: -Answer: They may result to non polar covalent compounds depending on molecular geometry. Explanation: A polar bond is a covalent link formed by two atoms in which the distribution of the bond’s electrons is uneven.
