Chemistry - Carboxylic acid and their Derivatives Question with Solution | TestHub

Concept - Those compounds which are more acidic than ${\mathrm{H}}_2{\mathrm{CO}}_3$ can gives effervescence of ${\mathrm{CO}}_2$ with aq. ${\mathrm{NaHCO}}_3$.
Release ${\mathrm{CO}}_2\uparrow$ gas with aq. NaHCO 3
$\Rightarrow [\text{ A.S. }{]}_{\text{Comp. }}>[\text{ A.S. }{]}_{{\mathrm{H}}_2{\mathrm{CO}}_3}$
$\to$ Option 1,2 and 3 gives effervescence of ${\mathrm{CO}}_2$ gas with ${\mathrm{NaHCO}}_3$
$\to$ Option (4) Not gives ${\mathrm{CO}}_2$ gas with ${\mathrm{NaHCO}}_3$.
