WebIn the electrolytic decomposition of water into its elements, a basic minimum of 2400 A flowing for 1 hour is needed to produce 1 m3of dry hydrogen (0°C, 760 mm of Hg); or, put another way, 2180 Ah are needed to produce the hydrogen contained in 1 m3of moisture-saturated gas (20°C, 760 mm of Hg). WebIt is obvious that, more the electronegative element the H attached to, the more will be its magnitude of H Bond. So it the hydrogen-bond strength follows order HF> H2O>NH3. Still, H2O has higher boiling point than HF, the reason is as follows. HF is a linear molecule, a molecule of HF can only form 2 hydrogen bonds (as ---H-F---H-F---H-F---).

WebComparing the melting points of benzene and toluene, you can see that the extra methyl group on toluene disrupts the molecule's ability to stack, thus decreasing the cumulative strength of intermolecular London dispersion forces.
