Re: H20
H20 is considered monodentate because only one lone pair bonds a central atom, while the other lone pair points away from the central atom. Hope this helps!

Re: H20
H2O is monodentate because in a molecule one atom can only bond to the TM once, so only one lone pair on the O atom can bond to a central atom. If you have two separate O atoms spaced out in the same molecule both can bond to an atom, which again is only one lone pair per atom.

Re: H20
The two lone pairs are too close for both to bond and be stable. Usually bidentate ligands have electron lone pairs that are far away and point to the same direction.

Re: H20
H20 contains both lone pairs on the oxygen but only one binding site between H2O and the central metal, therefore it is monodentate.
