Question

Discuss the polariy of a para nitrophenol and ortho nitrophenol, Where does the difference comes from.

Answer 1

• p-nitrophenol more polar than o-nitrophenol
• o-Nitrophenol has solid/strong intramolecular hydrogen bonds, yet p-nitrophenol has solid intermolecular H-bonds.
• p-Nitrophenol has strong intermolecular hydrogen bonds.
• These solid intermolecular strengths imply that has a low vapor weight
• Truth be told, the compound breaks down before it achieves an ordinary breaking point.
• In o-nitrophenol, the hydrogen bonds are connected with the contiguous nitro amass.
• The intramolecular strengths are much weaker than in the para isomer, so the vapor weight is much higher.
• The ordinary breaking point is till high (216 °C), however the vapor weight is sufficiently high that o-nitrobenzene is effortlessly steam refined.
