Draw molecules that satisfy the following prompts i-iii. All molecules must have 8-10 Carbon atoms AND exactly 2 Heteroatoms (i.e. atoms that are not carbon or hydrogen atoms). You may not use the same molecule twice for any parts of this question. You do not need to look up solubility information, but the answers must be reasonable. Also, the structures must be reasonable (improper structures, e.g. carbon with 5 bonds, or oxygen with one bond and no charge, will not...
