What conclusion does this model

support?

A. Slight negative charges around the

oxygen molecule and the slight positive

charges of hydrogen atoms form a

polar molecule.

B. The two hydrogen atoms are both

attracted to the negative oxygen atom,

sharing the electrons equally, forming a

nonpolar molecule.

C. Strong negative charge of oxygen

molecules is equally shared by the

hydrogen atoms, forming polar

molecules that exhibit hydrogen

bonding.

D. The two hydrogen atoms generate a

strong positive charge that attracts and

bonds with the weak negative oxygen

atom that exhibits ionic bonding.

The correct answer is A slight negative charge around the oxygen molecule and slight positive charge of the hydrogen atoms forms a polar molecule.

Explanation:

If we go through the chemical structure of water molecule, we will see that a molecule consiat of 2 hydrogen atoms and one oxygen atom. As the electro negativity of the oxygen atom is far greater than that of hydrogen atom, the oxygen atom attract the bonding electron pair towards itself. This ultimately result in the generation of bond polarity.

As oxygen attract the bonding electron pair towards itself the oxygen atom acquires slight negative charge. On the other hand the hydrogen atoms gets partial positive charge.

Now the partial positive charged hydrogen atoms and partial negative charged oxygen atom forms a polar molecule known as water.
