The compound which is not formed during the dry distillation of a mixture of calcium formate and calcium acetate is

Options

  1. Amethanal
  2. Bpropanal
  3. Cpropanone
  4. Dethanal

Correct answer

B. propanal

Step-by-step solution

Propanal is not formed during the dry distillation of a mixture of calcium formate and calcium acetate. (HCOO)2Ca→ Dry distillation HCHO+CaCO3(\mathrm{HCOO})_2 \mathrm{Ca} \xrightarrow{\text{ Dry distillation }} \mathrm{HCHO}+\mathrm{CaCO}_3\left(\mathrm{CH}_3\mathrm{COO}\right)_2 \mathrm{Ca} \xrightarrow{\Delta} \mathrm{CH}_3\mathrm{COCH}_3+\mathrm{CaCO}_3(HCOO)2Ca+(CH3COO)2Ca→Δ2CH3CHO+2CaCO3\begin{array}{r}(\mathrm{HCOO})_2 \mathrm{Ca}+\left(\mathrm{CH}_3\mathrm{COO}\right)_2\mathrm{Ca} \xrightarrow{\Delta} 2 \mathrm{CH}_3\mathrm{CHO} \\ +2 \mathrm{CaCO}_3\end{array}
