MCQ
Which one of the combinations will give propanaldehyde on dry distillation?
- A$(C_6H_5COO)_2Ca$ and $(HCOO)_2Ca$
- B$(CH_3COO)_2Ca$ and $(CH-3CH_2-COO)_2Ca$
- ✓$(CH_3-CH_2-COO)_2Ca$ and $(HCOO)_2Ca$
- D$(CH_3COO)_2Ca$ and $(CH_3COO)_2Ca$
✓
Answer
Correct option: C.
$(CH_3-CH_2-COO)_2Ca$ and $(HCOO)_2Ca$
c
Dry distillation of a mixture of calcium propionate and calcium formate gives propanaldehyde.
Dry distillation of a mixture of calcium propionate and calcium formate gives propanaldehyde.
$\left( CH _3- CH _2- COO \right)_2 Ca +( HCOO )_2 Ca \stackrel{\text { drydistillation }}{\longrightarrow} 2 CH _3 CH _2 CHO + CaCO _3$
