The Correct Option is A

Solution and Explanation

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

P-Block Elements

  • P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
  • P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.

P block elements consist of:
