Which of the following reactions of methane is incomplete combustion:

Options

A. `2CH_(4)+O_(2)overset("Cu/523K/100atm")rarr2CH_(3)OH`
B. `CH_(4)+O_(2)overset(Mo_(2)O_(3))rarrHCHO+H_(2)O`
C. `CH_(4)+O_(2)rarrC(S)+2H_(2)O(l)`
D. `CH_(2)+2O_(2)rarrCO_(2)(g)+2H_(2)O(l)`

Answer

C

Explanation

During incomplete combustion of alkanes with insufficient amount of air or dioxygen carbon black is formed which is used in the manufacture of ink, printer ink , black pigments and as filters. Thus, `CH_(4)(g)+O_(2)(g)overset("Incomplete")underset("combustion")rarrC(S)+2H_(2)O(l)`
