A polar covalent is the exact opposite. Answer: Polar covalent bonds (eg HCl) have a higher distortion(due to strong attraction by electonegative atom) of atoms participating in bond due to greater electonegativity difference between them (H=2.1 Cl=3 difference=0.9). Polar covalent bond compounds also have a higher melting and boiling points than non-polar covalent bond compounds due to the greater force of attraction between the atoms of the molecules. Polar covalent bonds always occur between non-metallic elements with a sufficient electronegativity difference to create polarity in the bond. covalent bond definition: 1. a chemical bond in which two atoms share one or more pairs of electrons that hold them together2. The electronegativity value for oxygen is 3.44, whereas the electronegativity value for hydrogen is 2.20. In polar covalent bonds, the electron spends more time with one atom than the other.

In polar covalent bonds, one atom has a stronger pull than the other atom and attracts electrons. Some bonds fit clearly into one category, such as C-C bonds (covalent), C-O bonds (polar covalent), or Na-O bonds (ionic). For example, tetrachloro-methane (carbon tetrachloride, CCl 4) has polar C—Cl bonds, but the tetrahedral arrangement of the four bonds about the central carbon atom causes the individual bond moments to cancel.
A coordinate covalent is a chemical linkage between two atoms where a lone pair of electrons are donated by a donor atom and accepted by an acceptor atom. In a polar covalent bond, sometimes simply called a polar bond, the distribution of electrons around the molecule is no longer symmetrical. Thas, a polar covalent bond is born.
If one atom really likes electrons,.
A coordinate bond (also called a dative covalent bond) is a covalent bond (a shared pair of electrons) in which both electrons come from the same atom.
