Question

--The magnitude of the forces "London" depends on
1. the molar mass of the substance only
2. the shape of the molecule only
3. the polarizability of the electronic cloud only
4. All of the above are incorrect

--Water in its solid state is less dense than in its liquid state this is due to
1. its large molar mass
2. its high polarizability
3. Its high surface tension
4. Its molecular geometry

---A substance where intermolecular forces are high is expected to have
1. high boiling point
2. low boiling point
3. Low surface tension
4. all are correct

---the boiling point of water depends on
1.he ambient temperature
2.amount of water to be evaporated
3.surface tension
-4.atmospheric pressure or applied pressure

Explanation / Answer

The boiling point of the water depends on the atmospheric pressure or applied pressure. Option 4 is right.

A substance where intermolecular forces are high is expected to have high boiling point. Option 1 is right.

Water in solid state is less denser than liquid water due to its molecular geometry. Option 4 is right.

The magnitude of the London dispersion forces deoendsdon the polarisibipola of the electron cloud only. Option 3 is right
