POLAR AND NONPOLAR MOLECULES

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What type of molecule is water
A
polar
B
nonpolar
C
neither
Explanation: 

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: -Thus, the electronegativity difference between oxygen and hydrogen atoms causes polarity in H2O molecules.

Detailed explanation-3: -Polar end of molecule attracts opposite charges on another water molecule (acts like magnet).
