MCQ
Indicate the incorrect statement:
  • A
    Number of hybrid orbitals formed is equal to no. of atomic involved.
  • ✓
    $2_{p x}$ and $2_{p y}$ orbitals of carbon can be hybridized to yield two new more stable orbitals.
  • C
    Effective hybridisation is not possible with orbitals of widely different energies.
  • D
    The concept of hybridization has a greater significance in the $VB$ theory of localised orbitals than $MO$ theory.
✓

Answer

Correct option: B.
$2_{p x}$ and $2_{p y}$ orbitals of carbon can be hybridized to yield two new more stable orbitals.
$2_{p x}$ and $2_{p y}$ orbitals of Carbon cannot be hybridized to yield $2$ more stable orbitals. This is because hybridization takes place between orbitals of different atoms thus the statement of option $B$ is incorrect.
