What is the most significant intermolecular force acting on the vinegar molecules? explain your answer. (2 points)
ii. draw a diagram of the intermolecular force acting on a vinegar molecule

Acetic Acid or Vinegar has London Dispersion Forces, Dipole Dipole forces and Hydrogen bonding forces.
Since Dipole Dipole is stronger than both hydrogen bonding and London Dispersion, the strongest one is dipole dipole.
I cannot draw a diagram, sorry. 

Idon't know hope someone you
