We’re being asked the best solvent for nonpolar solutes. Recall that the main idea in dissolution is like dissolves like, which means compounds with the same polarity and intermolecular force can dissolve each other.
Nonpolar solutes exhibit dispersion forces. We need to determine which solvent is the most nonploar.
So for this, we need to draw the Lewis structures of the given choices and determine their polarity.
Step 1: Determine the central atom in this molecule.
Step 2: Calculate the total number of valence electrons present and draw the Lewis structure for the molecule.
Step 3: Determine the polarity of the molecule.
Common laboratory solvents include acetone (CH3COCH3), methanol (CH3OH), toluene (C6H5CH3), and water.
Which of these is the best solvent for nonpolar solutes?
