$m-$nitrophenol $> o-$nitrophenol

Vedclass · Answer

(A, B, C, D) The boiling point depends on various intermolecular forces:
$(a)$ For isotopes,the boiling point increases with molecular mass: $T_2 > D_2 > H_2$.
$(b)$ For isomers,the boiling point decreases with branching due to a decrease in surface area: $n-$pentane $> 	ext{neo-pentane}$.
$(c)$ For noble gases,the boiling point increases with molecular mass due to stronger London dispersion forces: $Xe > Ar > He$.
$(d)$ $m-$nitrophenol exhibits intermolecular hydrogen bonding,while $o-$nitrophenol exhibits intramolecular hydrogen bonding. Intermolecular hydrogen bonding leads to the association of molecules,resulting in a higher boiling point: $m-$nitrophenol $> o-$nitrophenol.
All the given options represent correct orders of boiling point.

List-$I$	List-$II$
$A. PCl_5$	$I. \text{Tetrahedral}$
$B. BrF_5$	$II. \text{Square Planar}$
$C. BF_4^-$	$III. \text{Trigonal bipyramidal}$
$D. [Ni(CN)_4]^{2-}$	$IV. \text{Square pyramidal}$

Which of the following represents the correct order of boiling point?
