Hydrogen Bond is the strongest IMF because
it is temporary
H only has 1 electron and when shared unequally with O, N, or F it creates extreme poles
It is permanent
Hydrogen has a very strong electronegativity and pulls on the electrons
A strong IMF increases
boiling point
solubility
flammability
malleability
Viscosity is
the resistance to flow
the resistance to spread out
the ability to make sheets of metal
the ability to make wire
A weak IMF will result in a
high melting point
high viscosity
high surface tension
low surface tension
Why do oil and water not mix?
Water and oil have the same IMF
Water and oil's IMFs are too different in strength.
Why does water bead on a clean window?
Water has a strong IMF ~ high surface tension and stick together and resist spreading out
Water has a weak IMF ~ weak surface tension and stick together and resist spreading out
