Change 1,2-ethenediol into 1,2 ethynediol (HOCCOH) by removing one hydrogen atom from each carbon atom and replacing with a triple bond between the carbon atoms. Be sure to add the third rod to represent the triple bond. Draw a Lewis structure for 1,2-ethynediol. A. Identify the electron-pair and molecular geometry around each carbon and oxygen atom. B. What are the bond angles for C-C-O? For C-O-H? C. Can the molecule interconvert or “flip” between different structures in which the –OH group on the two carbon atoms occupy different orientations with respect to each other? If so, how does this happen? If not, why?
