10.3: Polar Covalent Bonds and Electrostatic Potential Maps
WEBJul 12, 2023 · Compounds with polar covalent bonds have electrons that are shared unequally between the bonded atoms. The polarity of such a bond is determined largely by the relative electronegativites of the bonded atoms.

WEBBonds between carbon and less electronegative elements are polarized so that carbon bears a partial negative charge and the other atom bears a partial positive charge. An example is the C–Li bond in methyllithium, CH 3 Li ( Figure 2.4 b).
6.2 Electronegativity and Polarity – Chemistry Fundamentals
WEBThe more strongly an atom attracts the electrons in its bonds, the larger its electronegativity. Electrons in a polar covalent bond are shifted toward the more electronegative atom; thus, the more electronegative atom is the one with the partial negative charge.
5.10: Electronegativity and Bond Polarity - Chemistry LibreTexts
WEBMay 18, 2021 · A bond in which the electronegativity difference between the atoms is between 0.5 and 2.1 is called a polar covalent bond. A polar covalent bond is a covalent bond in which the atoms have an unequal attraction for electrons and so …
7.2 Covalent Bonding - Chemistry 2e - OpenStax
WEBThis unequal distribution of electrons is known as a polar covalent bond, characterized by a partial positive charge on one atom and a partial negative charge on the other. The atom that attracts the electrons more strongly acquires the partial negative charge and vice versa.

WEBElectronegativity and Bond Type. The absolute value of the difference in electronegativity (ΔEN) of two bonded atoms provides a rough measure of the polarity to be expected in the bond and, thus, the bond type. When the difference is very small or zero, the bond is covalent and nonpolar.
6.4 Polarity of Molecules | Introductory Chemistry - Lumen …
WEBElectronegativity is a measure of the tendency of an atom to attract electrons (or electron density) towards itself. It determines how the shared electrons are distributed between the two atoms in a bond. The more strongly an atom attracts the electrons in its bonds, the larger its electronegativity.
Covalent bonding and electronegativity – Chemistry for the …
WEBWhether a bond is nonpolar or polar covalent is determined by a property of the bonding atoms called electronegativity. Electronegativity is a measure of the tendency of an atom to attract electrons (or electron density) towards itself. It determines how the shared electrons are distributed between the two atoms in a bond.
