Chemistry - CHEMICAL BONDING Question with Solution | TestHub

Explain Question :

Comparing physical properties based on intermolecular forces.

Concept:

Boiling Point and Van der Waals Forces.

Solution:

• Option 1: Incorrect. Solubility of Noble gases increases down the group (Xe > He) due to higher polarizability.

• Option 2: Incorrect. I₃^- is more stable than Cl₃^- due to the better availability of d-orbitals in Iodine.

• Option 3: Incorrect. Water has maximum density at 4°C, meaning it has minimum volume. Thus, V(0° C) > V(4° C).

• Option 4: Correct. Boiling point increases with molecular mass and surface area in alkanes because London dispersion forces increase.

Final Answer: Option (D)
