can you write the answer clearly to understand it thanks Solution Carbon monoxide vs. Carbon dioxide Main differences based upon their structure :- 1). Carbon dioxide ( CO 2 ) is composed of 1 carbon atom and 2 oxygen atoms on the other hand carbon monoxide CO) is composed by 1 carbon and 1 oxygen atom . 2). In CO 2 , surrounded oxygen atoms are covalently bonded with central carbon atom by double bond while in CO carbon and oxygen atoms are covalently bonded by triple bond in which carbon atom carry one unit negative charge and oxygen atom carry one unit positive charge and hence overall structure of CO is neutral . Differences based upon their Chemical properties:- 1). Carbon dioxide is produced by complete combustion of carbon in the presence of oxygen on the other hand carbon monoxide is produced by incomplete combustion of carbon . for e.g:- C (s) + O 2 (g) --------------------> CO 2 (g)    ( Complete combustion ) C (s) + 1/2 O 2 (g) -------------------> CO (g) ( Incomplete combustion ) . 2) . CO 2 serve as ligand in metal carbon dioxide complexes for e.g :- Li - R + CO 2 --------------> R CO 2 Li while CO form complexes with metals having lower oxidation number , in which CO act as ligand . for e.g :- Fe   +   5 CO ------------> Fe(CO) 5 3) . CO 2 used in Photosynthesis process i.e CO 2 reacts with water in atmosphere as : n CO 2 + nH 2 O --------------> ( CH 2 O) n + nO 2 on the other hand CO produce CO 2 and H 2 gases with water . for e.g :-  CO(g) +  H 2 O -----------------> CO 2 +    H 2 CO is very toxic and reactive gas . it is present rare in the air while CO 2 is non-poisoness gas . it is common gas in the air. CO 2 is required for plant life and it is most important greenhouse gas . .
