Rank the given solvents in decreasing order of their

Solution 1P

The four solvents are ethyl ether, water, ethanol, and dichloromethane.

Among these four solvents water is more polar solvent and dichloromethane is less polar solvent when compare to other given solvents. Ethanol is more polar than ethyl ether and less polar than water.

Hence, the decreasing polarity order of these four solvents is as follows;

Water > ethanol > ethyl ether > dichloromethane

The three solutes are sodium acetate, naphthalene, and 2-naphthol.

Among these three solutes sodium acetate is more polar compound because it is an ionic compound. 2-naphtanol is polar compound but less polar compound than sodium acetate. Naphthalene is non-polar compound.

Hence, the decreasing polarity order of these three solutes is as follows;

The guiding principle for the solubility is “like dissolves like”
