Which of the following reactions of methane incomplete combustion :

Answer»

`2CH_4+O_2 overset"Cu/523 K / 100 atm"to 2CH_3OH`
`CH_4+O_2 overset(Mo_2O_3)to HCHO+H_2O`
`CH_4+O_2 to C(s) + 2H_2O (L)`
`CH_4+2O_2 to CO_2 (s) + 2H_2O (l)`

SOLUTION :COMPLETE combustion of `CH_4` gives `CO_2` and `H_2O` . THEREFORE , reaction (c ) in which `CH_4` is converted into C and `H_2O`is an incomplete combustion reaction.
