💡 Solution & Explanation

o-nitrophenol p-nitrophenol Note: O N H O O Due to intramolecular H Bonding V P  of O nitrophenol will be higher. If one have V P 400   & the V P  of mixture is 520 mm of Hg, i.e. the V P  of other will be higher than 400, so if P is the V P  then it will of O nitrophenol O nitrophenol P nitrophenol P 400 520 P
