Which out of `N_(2)` and `H_(2)O` is polar and why ?

1.	Which out of `N_(2)` and `H_(2)O` is polar and why ?
Answer» Nitrogen `(N_(2))` is a homodiatomic molecule and is therefore non-polar. On the other hand, the geometry of `H_(2)O` is angular or bent with bond angle of `104.5^(@).` The polarities of the O-H bonds do not cancel out and it is of polar nature.
