Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The rule that refers to polar molecules dissolving polar and nonpolar dissolving nonpolar is
A
this dissolves that
B
like dissolves like
C
same dissolves same
D
here dissolves there
Explanation: 

Detailed explanation-1: -Like Dissolves Like. A simple way to predict which compounds will dissolve in other compounds is the phrase “like dissolves like". What this means is that polar compounds dissolve polar compounds, nonpolar compounds dissolve nonpolar compounds, but polar and nonpolar do not dissolve in each other.

Detailed explanation-2: -Generally, if all three of the intermolecular forces of attraction are roughly equal, the substances will be soluble in each other. This means that ionic or polar solutes dissolve in polar solvents, while non-polar solutes dissolve in non-polar solvents.

Detailed explanation-3: -"Like dissolves like” is an expression used by chemists to show the interaction of molecules due to different polarity. Polar substances WILL dissolve in Polar substances and Non-polar substances WILL dissolve in nonpolar substances.

Detailed explanation-4: -A good rule of thumb is to use is like dissolves like, which means that substances must have similar intermolecular forces to form solutions. A substance can dissolve in a solvent, and form a solution, if the solute and solvent are attracted to each other.
