Out of the following compounds which produce `CO_(2)` gas when treated with `NaHCO_(3)` ?
(i) Phenol (ii) 2, 4, 6-Trinitrophenol
(iii) Acetic acid (iv) 2, 4, 6-trimethylphenol.
(v) Ethyl alcohol.

Options

A. (ii), (iii), (iv)
B. (iii)
C. (ii), (iii)
D. (i), (iii)

Answer

C

Explanation

Both 2, 4, 6-trinitropgenol and acetic acid give effervescence with `NaHCO_(3)`. The other compounds are very weak acids and cannot evolve `CO_(2)` on reacting with `NaHCO_(3)`.
