I am really confused as to why 1) cyclopropyl has SP2 character, is it because of the strain of the ring that forces the orbitals to adopt a SP2 character? 2) does cyclobutyl and cyclpentyl also have this character or is the strain/thus the bond angles allow for a SP3 character.
Also would anyone know why SP3 carbons are prone to metabolic oxidation whilst SP2 carbons are metabolically resilient? I can not find anything on this online.
Many thanks in advance,
