Part A What is meant by the term polar covalent bond? O A polar covalent bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. A polar covalent bond is the attractive interaction of a hydrogen atom with an electronegative atom, such as nitrogen, oxygen or fluorine, that comes from another molecule or chemical group A polar covalent bond is a covalent bond in which electrons are shared unequally, being more attracted to...
