Part G. Molecules with Oxygen and Nitrogen. Organic molecules often contain the elements oxygen and nitrogen. Construct a model with the molecular formula C5H12O where the oxygen is bonded to one hydrogen. When a hydrogen is bonded to an oxygen or nitrogen, you need to draw that bond in a bond-line structure. Draw the bond-line structure of this model. What is the molecular geometry of oxygen in your structure? Draw three more constitutional isomers with the molecular formula C5H12O where the oxygen is bonded to one hydrogen. Structure Structure Structure Draw three more constitutional isomers with the molecular formula C5H12O where the oxygen is bonded to two carbon atoms. Structure Structure Structure
