- Hw problem wants 2 structures that have the same molecular formula but different connectivities for C3H4Chemistry is it the one on the right becuae the reaonance structure of the conj base is more delocalized/stable than the conj base of the left? can you draw a resonance of both so i can check my work? thanks guys10. Question shown in photo Vanillin (Figure 5, C8H8O3) is an organic compound extracted from the vanilla bean and is used to add flavor to drinks, food, and pharmaceuticals. While natural vanilla extract is composed of many different compounds, artificial vanillin is usually synthesized as a pure compound. As of 2001 only about 15% of the annual demand for vanillin was isolated as a natural product. Identify the hybridization of the labeled atoms in vanillin. a) i (sp2 ); ii (sp2 ); iii (sp2 ) b) i (sp2 ); ii (sp2 ); iii (sp3 ) c) i (sp2 ); ii (sp3 ); iii (sp2 ) d) i (sp3 ); ii (sp2 ); iii (sp2 )
