Explanation:
The boiling point of a compound is influenced by various factors including molecular weight, intermolecular forces, and intramolecular forces. In the case of p-nitrophenol and o-nitrophenol, the difference in their boiling points can be attributed to the presence of intermolecular hydrogen bonding in p-nitrophenol.
Intermolecular Hydrogen Bonding:
Intermolecular hydrogen bonding occurs between molecules of a compound. It is a strong type of dipole-dipole interaction in which a hydrogen atom bonded to an electronegative atom (such as nitrogen, oxygen, or fluorine) is attracted to another electronegative atom in a neighboring molecule.
p-Nitrophenol:
In p-nitrophenol, the -OH group is located at the para position (p-position) with respect to the nitro group (-NO2). The presence of the nitro group increases the electronegativity of the oxygen atom in the -OH group, making it more prone to form hydrogen bonds with neighboring molecules. This results in the formation of intermolecular hydrogen bonding in p-nitrophenol.
o-Nitrophenol:
In o-nitrophenol, the -OH group is located at the ortho position (o-position) with respect to the nitro group. Due to the close proximity of the nitro group, the -OH group in o-nitrophenol is unable to form strong intermolecular hydrogen bonds. Instead, it experiences intramolecular hydrogen bonding within the molecule itself. Intramolecular hydrogen bonding occurs when the hydrogen bond donor and acceptor are present within the same molecule.
Boiling Point:
Intermolecular hydrogen bonding is a stronger intermolecular force compared to intramolecular hydrogen bonding. It requires more energy to break the intermolecular hydrogen bonds in p-nitrophenol during the boiling process, resulting in a higher boiling point compared to o-nitrophenol.
Therefore, the correct answer is option C - there is intermolecular hydrogen bonding in p-nitrophenol.
