The Questions and Answers of In which of the following molecules the central atom does not have sp3 hybridization? There is an equivalent sharing of character and hence the hybrid orbital exhibit 50% s character and 50% p character. In case of sp 3 d, sp 3 d 2 and sp 3 d 3 hybridization state there is a common term sp 3 for which 4 sigma bonds are responsible. This is … 6 S-character and the stability of the anion: Each sp3 orbital has 1 part of s-character to 3 parts of p-character. In other words, it has 25% s-character and 75% p-character. Since the s orbital is closer to the nucleus and thus lower in energy than the p orbital, the electrons of sp3 hybridized species are held farther from the nucleus than those in sp2 (33% s-character) and sp (50% s-character) hybridized species.
