A polar covalent bond is a covalent bond in which the atoms have an unequal attraction for electrons and so the sharing is unequal. In a polar covalent bond, sometimes simply called a polar bond, the distribution of electrons around the molecule is no longer symmetrical.
A polar covalent bond forms between two atoms in which the electrons are unequally shared. People also asked Study Guides Chemistry Created By Brielle Cruickshank
The shared electrons in this type of bond means that the bonding atoms have an unequal number of electrons in their outermost orbitals. This is called a polar molecule because there is more electron density on one side than the other, making it slightly positive and negative at different points. The electrons are shared unequally.

What are examples of a polar covalent bond?
A water molecule, abbreviated as H2O, is an example of a polar covalent bond. The electrons are unequally shared, with the oxygen atom spending more time with electrons than the hydrogen atoms.
What is polar and nonpolar covalent bond?
A covalent bond that has an unequal sharing of electrons, as in part (b) of Figure 4.4. 1, is called a polar covalent bond. A covalent bond that has an equal sharing of electrons (part (a) of Figure 4.4. 1) is called a nonpolar covalent bond.
How do you know if a covalent bond is polar or nonpolar?
A polar covalent bond is a bond formed when a shared pair of electrons are not shared equally. This is due to one of the elements having a higher electronegativity than the other. The shared pair of electrons between an atom of hydrogen and an atom of bromine are not shared equally.
What is an example of nonpolar bond?
An example of a non-polar bond is the bond in chlorine. Chlorine contains two chlorine atoms. The electrons are shared equally because the electronegativity difference between the two atoms is zero.
Are there nonpolar covalent bonds?
Covalent bonds can be polar or nonpolar, depending on the electronegativity difference between the atoms involved.
What are polar and non-polar covalent bond?
Covalent bonds formed between atoms of the same kind are usually non-polar and the shared electrons are equidistant from both atomic nuclei. Polar covalent bonds are charged (positive as well as negative poles), whereas non-polar covalent bonds are not charged.
What is a non-polar covalent bond?
A non-polar covalent bond is a type of chemical bond that is formed when electrons are shared equally between two atoms. Thus, in an atom, the number of electrons shared by the adjacent atoms will be the same. The covalent bond is also termed as nonpolar because the difference in electronegativity is mostly negligible.
What is an example of nonpolar?
Nonpolar Molecule Examples Examples of homonuclear nonpolar molecules are oxygen (O2), nitrogen (N2), and ozone (O3). Other nonpolar molecules include carbon dioxide (CO2) and the organic molecules methane (CH4), toluene, and gasoline. Most carbon compounds are nonpolar.
