Question

1. NO₂

   1. How many VE are there?

   2. What is the electron geometry?

   3. What is the molecular geometry?

   4. What are the hybridized orbitals?

   5. Is the molecule polar or non-polar?

Answer 1

Answer 1):-

a)The total number of valance electrons in NO₂ = 17

Five electrons from N atom and twelve electrons from the two O atoms.

b)The electron geometry of NO₂ is trigonal-planar.

(lewis-Structure of NO₂)

c) The molecular geometry of NO₂ is bent (angular).

d) NO₂ is sp² hybridised.

e) NO₂ is a polar molecule. This is because of its bent molecular geometry.
