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: -The rule of thumb is that “like dissolves like". Polar/ionic solvents dissolve polar/ionic solutes and non-polar solvents dissolve non-polar solutes. For example, water is a polar solvent and it will dissolve salts and other polar molecules, but not non-polar molecules like oil.

Detailed explanation-2: -Since these molecules are both polar, they will form a solution when mixed together. We say they are miscible, which means these two liquids will make a solution.

Detailed explanation-3: -A substance (solute) dissolves in a solvent if the intermolecular interactions are similar in both the components; for example, polar solutes dissolves in polar solvents and non polar solutes in non polar solvents thus we can say “like dissolves like".
