Substance A will not dissolve in water. What can be said about substance A?

It is nonpolar.

It is polar.

It is saturated.

It is unsaturated.

It is non polar ... as polar dissolve polar ... like dissolve like! so A must be non polar.

Water molecule has dipole moment because H and O have electronegative differences. Solubility is only possible if boty substances (solute and solute) are like i. e either both must be polar or non-polar. So substance A will not dissolve because it is non-polar whereas water is polar molecule.
