Why is Homovalent resonance (occuring between same atoms) better than heterovalent resonance (occuring between atoms if two or more different elements)?
(By better I mean, it provides more stability)
I think it is because of better overlapping of p orbitals between those of same atoms due to similar size and energy level. I don't know if my reasoning is correct or not and want it to be verified.
I also read in an organic textbook which related it with molecular orbitals. However I am not much acquainted with MOT so trying to understand it was a hard time. So a simple concept would be appreciated.
And, Thanks in advance!
