The correct order of electronegativity of carbon in various hybridization states:

Options

  1. As p < s p 2 < s p 3
  2. Bs p > s p 2 > s p 3
  3. Cs p 2 > s p < s p 3
  4. Ds p = s p 2 < s p 3

Correct answer

B. s p > s p 2 > s p 3

Step-by-step solution

We know that more will be % s character in the hybrid orbitals more will be the tendency of the orbitals to attract the shared paired of electrons towards itself and consequently more will be the electronegativity. Now, the % s character in different hybridisation states of carbon is sp   =   50 % sp 2   =   33 . 3 % sp 3 = 25 % Hence, the electronegativity will be varied in the order: sp > sp 2 > sp 3
