Q. Ortho-nitrophenol is less soluble in water than p- and m- nitrophenols because:

Q. Ortho-nitrophenol is steam volatile whereas para-nitrophenol is not. This is due to
$1.$Intramolecular hydrogen bonding present in ortho-nitrophenol
$2.$Intermolecular hydrogen bonding present in para-nitrophenol
$3.$Intramolecular hydrogen bonding present in para-nitrophenol
$4.$Inter-molecular hydrogen bonding present in ortho-nitrophenol.

Q. Ortho-Nitrophenol is more volatile than $p$-nitrophenol because of :

Q. Assertion :Boiling point of p-nitrophenol is greater than that of o-nitrophenol. Reason: There is intramolecular hydrogen bonding in p-nitrophenol and intermolecular hydrogen bonding in o-nitrophenol.

Q. Assertion :p- Nitrophenol is a stronger acid than o-nitrophenol. Reason: Intramolecular H-bond makes o-isomer weaker than p-isomer.
