Among the following compounds, the one (s) that gives (gives) effervescence with aqueous `NaHCO_(3)` solution is (are) :
(I) `(CH_(3)CO)_(2)O` , (II) `CH_(3)COOH`
(III) `PhOH` , (IV) `CH_(3)COCHO`

Text Solution

Verified by Experts

The correct Answer is:
A
`(CH_(3)OH)_(2)O` reacts with `H_(2)O` to produce acetic acid `(CH_(3)COOH)`. Thus both `(CH_(3)CO)_(2)O` and `CH_(3)COOH` give effervescence with an aqueous solution `NaHCO_(3)`.
