QAIPMT-2006-Ch-2404: NEET 2006 Chemistry - Class 12 AIPMT-2006-Ch-2404 Solution: The correct order regarding the electronegativity of hybrid…

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

Multiple Choice Options

A $sp<sp^2<sp^3$
B $sp>sp^2<sp^3$
C $sp>sp^2>sp^3$
D $sp<sp^2>sp^3$

Step-by-Step Verified Solution

Among the three given hybrid orbitals, sp hybrid orbital is most electronegative. Contribution of s in sp hybrid orbital is maximum (50%) so this orbital is closer to nucleus. Naturally it will have greater tendency to pull electron towards it. Hence it becomes more electronegative and sp 3 becomes least electronegative as it has only 25% s-character.
