Answer:
(a)
The order of increasing normal boiling point for LiF, HCI, HF, and F2 is F2 < HF < HCI < LiF
Step-by-step explanation:
The ordinary limit of a substance is the temperature at which the vapour pressure of the fluid equivalents the outside pressure. The boiling limit increments with expanding intermolecular powers.
The order for expanding ordinary limit for LiF, HCI, HF, and F2 will be
F2 < HF < HCI < LiF
