Covalent Bonds [ENDORSED]

[Danieljm1B]

What is the difference between a covalent and a polar covalent bond?

[Jeril Joseph 1B]

Well, the difference between the two would be that covalent bonds are the sharing of electrons between nonmetals; whether polar or non polar. Polar covalent bonds have to do with a lack of symmetrical distribution of electrons in the bond. As a result, the molecule formed from the polar covalent bond would have a negative end and a positive end on certain sides of the atoms because there is an electronegativity difference between the atoms bonded in the polar covalent bond. Hope this helps.

[Chem_Mod]

Yes, covalent bonds refer to the types of bonds where electrons are shared; they can be either polar or nonpolar covalent bonds. Polar covalent bonds are a type of covalent bond where the electrons are not equally shared as described above (nonpolar covalent bonds occur where electrons are equally or almost equally shared in the covalent bond)

[hannabarlow1A]

Unless the bonded atoms are the same element, it is likely that the covalent bond has ionic characteristics/some polarity, since different elements possess different electronegativities and will therefore unequally share electrons.
