Why does the E2 reaction require an anti-coplanar relationship between the beta-hydrogen and the leaving group X? a) Because the C-X bond must be equatorial to react. b) Because it maximizes overlap between the beta C-H o orbital the C-X o* orbital. c) Because it maximizes overlap between the C-H o* orbital and the C-X o orbital. d) Because the staggered conformation maximizes steric repulsion. e) Because this conformation will lead to the more substituted alkene.
