Detailed explanation-1: -The unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles-a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side).
Detailed explanation-2: -A polar molecule is a molecule in which one end of the molecule is slightly positive, while the other end is slightly negative.
Detailed explanation-3: -Polar Bonds polar bond: a covalent bond that has opposite partial charges on each side (one side partially positive and one side partially negative), because of unequal sharing of electrons. For example: The bond between H and Cl in the H-Cl molecule is a polar bond.
Detailed explanation-4: -Because oxygen and hydrogen attract the shared electrons unequally, each end of the V-shaped H2O molecule adopts a slightly different charge. The area around the oxygen is somewhat negative compared to the opposite, hydrogen-containing end of the molecule, which is slightly positive.
Detailed explanation-5: -Water is a “polar” molecule, meaning that there is an uneven distribution of electron density. Water has a partial negative charge ( ) near the oxygen atom due the unshared pairs of electrons, and partial positive charges ( ) near the hydrogen atoms.
