Chemistry - GOC Question with Solution | TestHub
For the following given compound
Number of correct statement(s) (1) Correct acidic strength order is: (2) Compound (S) has '5' resonating structures (3) Correct acidic strength order is : (4) Out of '8' only '2' are insoluble in aqueous NaOH
(5) Total molecular mass of gas evolved when given compounds are treated with one by one is 126 gm (6) Compound (Q) is more acidic than compound (W) due to H-bonding. (7) Out of '8' only '7' will evolve gas with Na metal
Answer:
Solution:
Statement (1) is correct: Picric acid (U) > Carbonic acid (T) > Phenol (S) > Methanol (V).
Statement (2) is correct: The phenoxide ion formed from phenol (S) has 5 resonating structures.
Statement (3) is incorrect: The correct acidic strength order is P (salicylic acid) > H₂CO₃ > W (p-nitrophenol) > R (benzyl alcohol).
Statement (4) is incorrect: Only R (benzyl alcohol) and V (methanol) are insoluble in aqueous NaOH, while the rest are soluble.
Statements (5), (6), and (7) are incorrect based on standard organic reactivity principles.
