Solution:

The degree of hydrogen holding predominantly relies upon

(I) Electronegativity

(ii) Number of hydrogen iotas accessible for holding.

Among oxygen, fluorine and nitrogen, the expanding request of their electro negativities are N < O < F.

Hence, the normal request of the degree of hydrogen holding is HF > H2O > NH3.

Yet, the genuine request is H2O > HF > NH3.

Despite the fact that fluorine is more electronegative than oxygen, the degree of hydrogen holding is high in water.

There is a lack of hydrogens in HF, while there are the absolute perfect quantities of hydrogens in water. Subsequently, just straight chain holding happens.

Then again, oxygen shapes an immense ring-like design through its high capacity of hydrogen holding.

The degree of hydrogen holding is restricted if there should be an occurrence of alkali, since nitrogen has just 1 solitary pair. Thusly, it can’t fulfill all hydrogens.
