ANSWERS NEEDED ASAP

My friends and I are really confused in chemistry right now, and we could REALLY use some help. When you give answers to the questions below, we would really appreciate an explanation as well so we can try and get an understanding.

1.) Do you think the forces holding water molecules to other water molecules are stronger or weaker than the forces holding rubbing alcohol molecules to other rubbing alcohol molecules?

2.) Do you think the forces holding rubbing alcohol molecules to other rubbing alcohol molecules are stronger or weaker than those holding water molecules to other water molecules?

3.) Hot chocolate mix often mixes more smoothly with milk- which contains fats- than it does with water. What type of molecules- polar or nonpolar- are fats if the hot chocolate mixes well with it?

4.) What can you tell about the relative strengths of the IMFs from the temperatures reached by wetted thermometers

1 and 2 the forces holding water molecules together are stronger than the forces holding alcohols molecules together these forces are stronger in water due to hydrogen bonding the intermolecular forces forces that hold the water together are stronger than alchol because water has hydrogen bonding hydrogen bonding is hydrogen being attracted to oxygen or flourine or chloroine the electronegativity differences are larger the forces holding the bonds are stronger its like hydrogen is holding on to oxygen strongly different types of forces are lomdon dispersion forces like helium which have low boiling point they have nothing holding them together water has hydrogen bonds alcohol doesnt have the hydrogen bonds water has and geometry vsper model polar and hydrogen bonds as water so theyre weaker.
