11. 3,4-Dihydropyran is a reagent commonly used as a protecting group for alcohols in organic synthesis. Is it possible to draw a resonance structure with the lone pair? What is the hybridization of the heteroatom? Draw a valence bond orbital diagram to show the location of the lone pair (you do not need to draw any orbitals to show $$?$$ bonds). In what orbital are the electron pairs located?
