Select the CORRECT order of boiling point?

Options:

Answer:
A
Solution:

Boiling point increases with molar mass and London dispersion forces.

C₃F₈ > C₃H₈ because fluorine increases molar mass and polarizability → stronger van der Waals forces.

(B) is wrong because branching decreases boiling point (neo-pentane < iso-pentane).

(C) is not correct due to isotopic effect being small and not matching given order.

(D) is wrong because NH₃ has hydrogen bonding, so its boiling point is higher than SbH₃.
