Draw the structures of: water, glycerol, ethylene glycol, acetone, hexane, and methanol. Name and briefly describe the intermolecular attractive forces (IMAF) you would expect to find for each of the drawn structures. Be sure to include the viscosity and density for ethylene glycol (also called glycol), glycerol (also called glycerine) and the denisty of mineral oil (also called paraffin oil)--and also, include what the denisties are of acetone, hexane, methnol, and water.
