Question
All allotropic form of carbon when burnt in the presence of oxygen, they produce:
- Carbon dioxide
- Carbon monoxide
- Carbon dioxide and hydrogen
- Both A and B
Hint:
Combustion can take place in excess amount of oxygen and also in limited amount.
The correct answer is: Both A and B
The correct option is d) both A and B.
When the allotropes of carbon burn in the presence of air carbon dioxide is formed and when it burns in the absence of air carbon monoxide is formed.
When oxygen is limited the combustion is incomplete and therefore, carbon monoxide is formed.
