So this is the case: liquid methanol, CH3OH is being prepared to be poured into a beaker of water.
(THERE CAN BE MORE THAN ONE ANSWER FOR Q1-3)
1) What intermolecular forces are broken in the methanol when these substances are mixed?
2) What intermolecular forces are broken in the water when these substances are mixed?
3) What intermolecular forces are formed in the solution when these substances are mixed?

Look up each of the four types of forces in your text and answer the best you can giving reasons for your answer. We shall be happy to provide comment.

1) i think this one is hydrogen bonding because in CH3OH, the H is bonded to an O. I think my teacher said all bonds have a tiny bit of dispersion force, but the main force is the H-bond. I am also confused, isn't h-bond also considered a dipole-dipole interaction? it's polar.
but i think i would answer hydrogen-bond + dispersion force
(based on what teacher said that all bonds have some kind of dispersion force) OR is he wrong? dispersion is only for non-polar?
2) i think i would answer h-bond and dispersion again.
again, if it was INTRmolecular force then it would be dipole-dipole but it is talking about INTERmolecular so it would be h-bond. i based the dispersion that all molecules contain a tiny bit of dispersion force.
3) i don't really get this one. so is this saying CH3OH + h20 = what type of force formed?
i think h-bond since the O can be connected to the H?
GAHHHH I AM SO CONFUSED
