In general, substances with stronger intermolecular forces have ____ boiling points than those with weaker intermolecular forces
|
|
higher
|
|
|
lower
|
Explanation:
Detailed explanation-1: -The boiling point of a substance is proportional to the strength of its intermolecular forces – the stronger the intermolecular forces, the higher the boiling point. By comparing the boiling points of different substances, we can compare the strengths of their intermolecular forces.
Detailed explanation-2: -Higher melting and boiling points signify stronger noncovalent intermolecular forces. Consider the boiling points of increasingly larger hydrocarbons. More carbons means a greater surface area possible for hydrophobic interaction, and thus higher boiling points.
Detailed explanation-3: -Stronger intermolecular forces
