Polarity
Definitions
bond polarity
The bond or the molecular polarities are related to the electronegativities of the atoms or the molecules.
POLAR - A polar molecule usually forms when the one end of the molecule is said to possess a number of positive charges and whereas the opposite end of the molecule has negative charges.
NON-POLAR - A molecule which does not have the charges present at the end due to the reason that electrons are finely distributed and those which symmetrically cancel out each other are the non- polar molecules.
molecule polarity
A polar molecule is a chemical species in which the distribution of electrons between the covalently bonded atoms is not even

quote
“A state or a condition of an atom or a molecule having positive and also negative charges, especially in case of magnetic or an electrical poles.”
How to predict polarity?
-
Find the difference of electronegativity. if the difference is from 0 to 0.4, it will be non-polar, if it is from 0.4 to 1.7 then the bond will appear polar. If it is not any of these it will be an ionic bond.
Analyze and see if the molecules are asymmetric or symmetric. When they are symmetric they usually are non-polar, and polar if asymmetric

FUN FACTS!
Around 1935, it was the American chemist Linus Pauling that developed a scale of electronegativity to describe the attraction an element has for electrons in a chemical bond.
A magnet has a polarity, in that one end is the "north" and the other is the "south".
