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

(a) Both are soluble in $\mathrm{NaOH}$. Hence, inseparable. (b) Only benzoic acid $\left({\mathrm{C}}_6{\mathrm{H}}_5\mathrm{COOH}\right)$ is soluble in $\mathrm{NaOH}$ and ${\mathrm{NaHCO}}_3$, while benzyl alcohol $\left({\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{CH}}_2\mathrm{OH}\right)$ is not. Hence, separable. (c) Although $\mathrm{NaOH}$ can enable separation between benzyl alcohol $\left({\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{CH}}_2\mathrm{OH}\right)$ and phenol $\left({\mathrm{C}}_6{\mathrm{H}}_5\mathrm{OH}\right)$ as only the latter is soluble in $\mathrm{NaOH}$. However, in ${\mathrm{NaHCO}}_3$, both are insoluble. Hence, inseparable. (d) $\alpha$-Phenylacetic acid $\left({\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{CH}}_2\mathrm{COOH}\right)$ is soluble in $\mathrm{NaOH}$ and ${\mathrm{NaHCO}}_3$, while benzyl alcohol $\left({\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{CH}}_2\mathrm{OH}\right)$ is not. Hence, separable.
