Which of the following is incorrect order of boiling point ?

Options:(select one or more)

Answer:

A, C, D

Solution:

(A) Halogens: The correct order is $F_{2} < C l_{2} < B r_{2} < I_{2}$ due to increasing van der Waals forces with molecular size.

(C) Aluminum Halides: $A l F_{3}$ is highly ionic with a giant lattice structure, giving it a much higher boiling point than the covalent dimers ( $A lC l_{3}$ , $A lB r_{3}$ , $A l I_{3}$ ).

(D) Hydroxybenzaldehydes: Ortho-hydroxybenzaldehyde forms intramolecular H-bonds, whereas the meta-isomer forms stronger intermolecular H-bonds, making the meta-isomer's boiling point higher ( $or t h o < m e t a$ ).
