Identify the compounds in the following.

H-C≡C-H + H₂O xrightarrowHg²⁺/H₂SO₄ [A] xrightarrow[K₂Cr₂O₇/H₂SO₄][Oxidation] [B] xrightarrow[(ii)…

$\text{H}-\text{C}\equiv\text{C}-\text{H} + \text{H}_2\text{O} \xrightarrow{\text{Hg}^{2+}/\text{H}_2\text{SO}_4} [\text{A}] \xrightarrow[\text{K}_2\text{Cr}_2\text{O}_7/\text{H}_2\text{SO}_4]{\text{[Oxidation]}} [\text{B}] \xrightarrow[(ii)\text{ dry distillation}]{\text{(i) } \text{Ca(OH)}_2} [\text{C}]$

Answer

Answer

A - ethanal: CH3CHO

B - ethanoic acid: CH3COOH

C - propanone: CH3COCH3

A = ethanal ($\mathrm{CH_3CHO}$) B = ethanoic acid ($\mathrm{CH_3COOH}$) C = propanone ($\mathrm{CH_3COCH_3}$)
