Question

circle the odd one out giving appropriate reason acid rain, oxides of Nitrogen, oxides of sulphur, carbon dioxide​

Answer 1

I think Carbon dioxide is the odd one out.

Because Acid rain, oxide of Nitrogen and oxide of sulphur are related to each other as oxides of sulphur are constituents of Acid rain.

Answer 2

i think its CO2 or carbon dioxide as its contribution towards the acid rain is negligible

whereas the other two oxides contribute highly towards acid rain which is the first option

so the answer is CO2
