Among `NH_3, `H_2O` and HF which would you expect to have highest magnitude of hydrogen bonding? Why?

Out of 'H-H' and 'Cl-Cl' bonds, which is expected to have higher bond enthalpy and why?

Amongst H_2 O, H_2 S, H_2 Se and H_2 Te , the one with the highest boiling point is: H_2 O because of hydrogen bonding, H_2 Te because of higher molecular weight, H_2 S because of hydrogen bonding, H_2 Se because of lower molecular weight.

Out of O_2 and N_2 molecules which is expected to have greater bond energy? Explain why it is so.

Hydrogen bonding is present in NH_3 and H_2O What are different types of hydrogen bonds?
