Catalytic converters are fitted into automobiles to reduce the emission of
harmful gases. Catalytic converters change unburnt hydrocarbons into:
a. carbon dioxide and water
b. carbon monoxide
c. methane
d. carbon dioxide and methane
The answer is the option (a) carbon dioxide and water
Explanation: Carbon monoxide is a lethal gas even in low concentration and hence option ‘b’ is incorrect. Methane is hydrocarbon and hence options ‘c’ and ‘d’ are ruled out
