MCQ
Indicate the incorrect statement:
  • A
    Number of hybrid orbitals formed is equal to no. of atomic involved.
  • B
    2px​ and 2py​ 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

  1. 2px​ and 2py​ orbitals of carbon can be hybridized to yield two new more stable orbitals.

Explanation:

2px​ & 2py​ 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.
