For two non-metals which have similar electronegativities, a non-polar covalent bond will be formed wherein the atoms equally share electrons. A slightly larger electronegativity difference (0.3-1.4) results to a polar covalent bonding, wherein the electrons are unequally shared...
In the case of water, we know that the O-H covalent bond is polar, due to the different electronegativities of hydrogen and oxygen. What must be always true if a covalent bond is polar? A molecule is polar if the shared electrons are equally shared. A molecule is nonpolar if the ...

A polar covalent bond is different from a nonpolar covalent bond because the atoms in a polar covalent bond do not share electrons equally. During a...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your t...
A covalent bond is classified into two categories based on its extent of charge separation and these categories are polar covalent and nonpolar covalent bonds. In a nonpolar covalent bond, no charge separation arises. In contrast, a polar covalent exhibits a charge separation due to the une...

A molecule is polar if one part of it has a partial positive charge, and another part has a partial negative charge. In abond, atoms can either share electrons (covalent) or give them up (ionic). The atom that holds the electrons closer will thus be more negatively charged than the oth...
