A) vapours of o-nitrophenol are carried by steam because of its lower boiling point due to chelation.
B) vapours of o-nitrophenols are carried by steam because of its lower boiling point and solubility in steam.
C) vapours of o-nitrophenol are carried by steam because its boiling point is reduced by steam.
D) vapours of p-nitrophenol are carried by steam because of its lower boiling point.
Correct Answer: A
Solution :
[a] Only o-nitrophenol is capable of forming intra molecular H-bonding (chelation) which leads to its lower b.p. (less than \[{{100}^{o}}C\]) and also lower solubility in water (steam).You need to login to perform this action.
