CHXI04:CHEMICAL BONDING AND MOLECULAR STRUCTURE

313637 Ortho-nitrophenol is less soluble in water than p- and m-nitrophenols because:

1 o-nitrophenol is more volatile steam than p-isomers
2 o-nitrophenol shows intramolecular H bonding
3 o-nitrophenol shows intermolecular H bonding
4 Melting point of o-nitrophenol is lower than those of m- and p-isomers.
