Hydrogen Bond
- oxygen (high electronegativity) electrons pulled towards o2 nucleus- giving o2 partial (-) charge and hydrogen partial (+) charge- covalent bond forms with hydrogen atoms due to asymmetrical distribution of electrons- electrical attraction between the partial (+) & (-) charges on water molecules from the BOND
Water is liquid at room temperature
high boiling point = 100C~ heat energy need to break the hydrogen bonds first~ to increase the movement of molecules (kinetic energy), which increases the temp
Water is the universal solvent
