(a) Represent all products and reactants using VSEPR three dimensional sketches. Include hydrogen atoms. If there are any stereogenic centres present, indicate these with an asterisk (*). If none are present, write a sentence to state this.


(b) Fill in the table on your template to indicate how/if shape and hybridization about C1, C2, C3, and C4 change during this reaction. To do this, sketch, label and populate (with the central atom valence electrons) the hybridized orbitals (and any remaining unhybridized orbitals)
