NEET Solved Paper 2014 Question 42
Question: Which of the following will not be soluble in sodium hydrogen carbonate? [AIPMT 2014]
Options:
A) 2, 4, 6-trinitrophenol
B) Benzoic acid
C) o-nitrophenol
D) Benzenesulphonic acid
Show Answer
Answer:
Correct Answer: C
Solution:
- While 2, 4, 6-trinitrophenol, benzoic acid and benzene sulphonic acid are soluble in $ NaHCO _3 $ . This reaction is possible in forward direction if acid is more acidic than $ H _2CO _3 $ . O-nitrophenol is less acidic than $ H _2CO _3 $ . Hence, it is not soluble in sodium hydrogen carbonate.
