A colourless gas '$$x$$' forms a brown coloured gas '$$y$$' when mixed with air. $$x$$ and $$y$$ could be :

A$$NO,N{ O }_{ 2 }$$
Correct Answer
B$$NO,{ O }_{ 2 }$$
C$$N{ O }_{ 2 },{ N }_{ 2 }{ O }_{ 4 }$$
D$$NO,{ N }_{ 2 }{ O }_{ 4 }$$

Solution

Nitric oxide is a colorless, flammable gas with a slight odor. Nitrogen dioxide is a deep red-orange gas that is poisonous but not flammable. When $$ NO $$ comes in contact with air it oxidizes and following reaction takes place.

$$2NO+{ O }_{ 2 }\longrightarrow 2N{ O }_{ 2 }$$

Hence, 'x' is $$ NO $$ and 'y' is $$ { NO }_{ 2 } $$.
