o-nitrophenol can be easily steam distilled whereas p-nitrophenol cannot be. This is because of :
a. strong intermolecular hydrogen bonding in o-nitrophenol
b. strong intramolecular hydrogen bonding in o-nitrophenol
c. strong intramolecular hydrogen bonding in p-nitrophenol
d. dipole moment of p-nitrophenol is larger than that of o-nitrophenol
