The correct order regarding the electronegativity of hybrid orbitals of carbon is:

Step-by-step solution

In s p, s p^2 and s p^3 hybrid orbitals, the s -orbital character is 50 %, 33.3 % and 25 % , respectively, and because of the higher s -orbital character, electronegativity, increases. Related Theory The electrons of s p^3 hybridized atom are farther from the nucleus than those in s p^2 hybridized species. Therefore, s p^2 hybrid species are more stable than s p^3 hybrid species. This is because the stability is greater when the electrons are close to the nucleus.
