Given the distribution of charges shown in this water molecule, why is it called polar?

Of the substances Xe, CH3Cl, and HF, which has:(a) The smallest dipole–dipole forces?

1,3-Propanediol can form intramolecular as well as intermolecular hydrogen bonds. Draw a structure of 1,3-propanediol showing an intramolecular hydrogen bond.

Propanol (PrOH) and methyl methacrylate (MMA) asso-ciate in solution by an intermolecular force, forming an adduct represented as PrOH•MMA. The equilibrium con- stant for the association reaction is Kc = 0.701 at 298 K. (b) Draw a plausible structure for the PrOH • MMA adduct. Use to signify an intermolecular interaction.
