Carbon monoxide is prepared by

A

heating formic and with conc. `H_(2)SO_(4)`

B

heating potassium ferrocyanide with conc `H_(2)SO_(4)`

C

heating malonic acid with `:P_(2)O_(10)`

D

hydrolysis of `Mg_(2)C_(3)`

Text Solution

Verified by Experts

The correct Answer is:
A, B
`HCOOH overset(Delta)toH_(2)O + CO , K_(4)[Fe(CN)_(6)]+6H_(2)SO_(4)+6H_(2)Oto 2K_(2)SO_(4)+FeSO_(4)+3(NH_(4))_(2)SO_(4)+6CO`
Malonic acid gives `C_(3)O_(2)` and `Mg_(2)C_(3)` gives `1` propyne.
