Answer:
The four unusual properties of water that are in direct result of hydrogen bonding are:
1) high boiling point and freezing point. There hydrogen bond in water makes it very slow to boil and freeze.
2) has the highest surface tension among all the liquid.
3) high heat of vaporization. Has a heat of vaporization of 41 kJ/mol.
4) strong intermolecular forces makes water have low vapor pressure, low viscocity, and highly cohesive.
