Question

the factors on which electronegativity depends on a)valence state of atom b) hybridisation c)both valence state and hybridisation d)none of the mentioned
​

Answer 1

Answer:

Greater the s character of the hybrid orbitals, greater is the electronegativity. Thus, a carbon atom having sp hybrid orbital with 50% s character is more electronegative than those possessing sp

hybridised orbitals.

−C≡CH is sp hybridised, hence, it is most electronegative.
