Hydrogen bond

why maximum no. of H-bonds in HF is 2, whereas that in water is 4??
(refer to the highlighted portion..)

and why are the bond lengths different for different H-bonds from the same molecule? (in the pic, bond lengths are 1.81 A, 1.79A, and 1.84A)..

Shreyan, pls see carefully......in HF, the total no. of bonds is two (one is H-F and the other is H...F)

I am not sure about water.......with the same logic as above, water should have total of 4 bonds....... H-O (2 bonds) and H....O (2 bonds)
