What is POLAR BOND  andWhat is POLAR COVALENT BOND Po

SOLUTION

Polar Covalent Bonds

Have you ever seen two children play and one child acts like a bully toward the other child? The bully child seems to spend more time playing with the toy than the other child. They are not equally sharing the toys.

This unequal sharing also happens with a type of bond called polar covalent bonding. Polar covalent bondingis a type of chemical bond where a pair of electrons is unequally shared between two atoms. In a polar covalent bond, the electrons are not equally shared because one atom spends more time with the electrons than the other atom. In polar covalent bonds, one atom has a stronger pull than the other atom and attracts electrons. Remember how electrons carry a negative charge? Well, when electrons spend more time with one atom, it causes that atom to carry a partial negative charge. The atom that does not spend as much time with the electrons carries a partial positive charge. To remember a polar covalent bond, instead say 'puller covalent,' and remember one atom has more 'pull' on electrons than the other atom.

Polar Bond Definition

A polar bond is a covalent bond between two atoms where the electrons forming the bond are unequally distributed. This causes the molecule to have a slight electrical dipole moment where one end is slightly positive and the other is slightly negative.
Water (H₂O) is a polar bonded molecule. The electronegativity value of oxygen is 3.44, while the electronegativity of hydrogen is 2.20. The inequality in electron distribution accounts for the bent shape of the molecule. The oxygen "side" of the molecule has a net negative charge, while the two hydrogen atoms (on the other "side") have a net positive charge.
