Question

Identify the incorrect statement(s) with respect to CO :

• A. it combines with water to give carbonic acid.
• B. it combines with haemoglobin of the blood.
• C. it is a powerful oxidising agent.
• D. CO is weak field ligand.

Answer 1

Answer: (A), (C), (D)

The correct options are
A it combines with water to give carbonic acid.
C it is a powerful oxidising agent.
D CO is weak field ligand.

CO do not combine with water and do not produce carbonic acid where as carbon dioxide do.

Carbon monoxide is harmful when breathed because it displaces oxygen in the blood and deprives the heart, brain, and other vital organs of oxygen.

CO is not only a powerful oxidising agent but also redusing agent.

CO is strong field ligand.

Hence options A,C & D are correct.
