The best method to separate the mixture of ortho and para nitrophenol

1.	The best method to separate the mixture of ortho and para nitrophenol (1:1) is
Answer» steam distillation crystallization vaporization color spectrum Solution :In `o-nitrophenol`, because chelation (intramolecular hydrogen BONDING) is possible, hydrogen bonding with the solvent water molecules is hindered and hence, solubility is lowered. MOREOVER, SINCE chelation CAUSES the `o-compound` to behave as a monomer, this isomer will be more volatile than the corresponding `m-` and `p-isomers`. Thus, the effects of chelation are lower solubility and greater volatility in the `o-nitrophenol`, thereby enabling it to be separated from its `m-` and `p-isomers` by steam distillation. Howerver, `o-isomer` may also be separated from the `p-isomer` by crystallization or by CHROMATOGRAPHY.
