How does hydrogen bond deduce water molecule properties? (Melting,boiling...) their angles

Question

anonymous · Answer

The hydrogen bonding of water molecules allows: water to have a higher boiling point (100 degrees Celsius) than other covalent molecular substances (which have -ve ones). This also applies to melting point. This is because hydrogen bonds are 10x stronger than covalent bonds. Water molecule angles are arranged quite uniquely in ice form due to hydrogen bonding, minimizing the distance between molecules due to high electrostatic attractions.

"deduce" ? Or explain?

"This is because hydrogen bonds are 10x stronger than covalent bonds"

This is incorrect, what you meant was "$\color{red}{than~london~ dispersion~forces}$".

Hydrogen bonds are $inter$molecular forces $<40~kJ/mol$.

Covalent bonds are $intra$molecular forces these vary depending on what atoms are on opposite sides of the bond as well as other atoms near by that may donate or withdraw electron density. For example, a C-C bond is $350~kJ/mol$, while a C-H bond is about $400~kJ/mol$.
