Question

The bonds between hydrogen and oxygen in a water molecule are classified as(1) polar covalent

Answer 1

Polar covalent is the answer. 

Because:- An ionic bond is incorrect because it is when electrons are transfered between atoms and it gives them a charge. It also cannot be metallic. Now, we know that it is covalent, but which kind? and why? A nonpolar covalent bond is when electrons are shared between the atoms, but it is shared equally. But since in our molecule here, we know that it is not being shared equally, therefore, making our answer A polar covalent bond. :)
Also, another point is that since covalent bonds are always neutral, and water has a pH of 7, it is neutral, and we need the answer to be covalent. 

Answer 2

Polar covalent. This is due to the fact the the oxygens have a much higher electronegativity than the hydrogen, so it pulls the molecule into a bent shape. The reason it is covalent is because both elements are nonmetals.
