Answer #1

1) melting points

melting points of polar molecules are in gneeral lower than the pure ionic compounds.

2) electrical conductivity in aqueous solutions.

Polar molecule either do not conduct electricity or to a very small extent while that of aqueous ionic solutions conduct a large amount of electricity.

The others may not be able distinguish polar form ionic compounds ,

as both dissolve in plar olvents by and large.

none conduct electricity in solid state

both do not dissolve in non-polar solvents.
