Why is water considered a polar molecule?

A. The molecule has no overall charge.
B. The oxygen and hydrogen atoms share electrons equally.
C. The atoms in the molecule have partial charges.
D. The molecule can only attract positive charges.

I personally deduct that it is C but I would love some other opinions! :)

Answer :

The answer is C. Oxygen tends to be slightly negative because of electron sharing with the two hydrogen atoms.

The temporal characteristics of the charges allow to find the correct answer for the polar molecules is:

       B. The oxygen and hydrogen atoms share electrons equally.

     

The electrons that form the bonds in the molecules can be distributed in several ways, giving two types of molecules:

  • Nonpolar. They are the molecules where in the middle the electrons are uniformly distributed and therefore the molecule does not have partial charges.
  • Polar. They are molecules where on average the electrons are closer to one atom than the other, in this case we can have some partial charge on each atom.

Let's analyze the claims:

A) False. These are nonpolar molecules.

B) False. Oxygen atoms share two electrons and hydrogen field one.

C) True. On average, electrons stay closer to the oxygen atom than to the hydrogen atom, therefore there is a partial negative charge on oxygen and a partial positive charge on hydrogens.

d) False. The molecules have equal positive and negative charges.

In conclusion using the temporal characteristics of the charges we can find the correct answer for the polar molecules is:

     B. The oxygen and hydrogen atoms share electrons equally.
