Question
Why are most molecular compounds (covalent) insoluble in water but often soluble in organic solvents?
Correct Answer
Option B is the correct answer.
Detailed Explanation
Most molecular compounds are insoluble in water because they release too little energy when they dissolve to overcome the intermolecular forces. They are often soluble in organic solvents because both the molecular compound and the organic solvent experience van der Waals forces, allowing for favorable interactions.
Hint
"Like dissolves like"—similar intermolecular forces promote solubility.
