Question

Consider the following sequence of conversion. $\underbrace{2NO +O_2}_{(X)}$ ${<=>}$ $\underset{\text{(Y)}}{ {2NO2}}$ ${<=>[\text{Cool}][\text{heat}]}$ $\underset{\text{(Z)}}{ {N2O4}}$ $X$, $Y$ and $Z$ can be described as

• A. a
• B. b
• C. c
• D. d

Answer 1

Answer: (A)

a

Answer 2

$\underbrace{2NO +O_2}_{\text{Colourless gases}}$ ${<=>}$ $\underset{\text{Brown, paramagnetic gas due to presence of an odd electron}}{ {2NO2}}$ ${<=>[\text{Cool}][\text{Heat}]}$ $\underset{\text{Colourless, diamagnetic solid}}{ {N2O4}}$
