ROAD MAP. A, B, and C are alkyl iodides with a molecular formula of C6H11I. Both compounds A and B react with Na - OCH3 in DMSO to give the same trisubstituted alkene DO. Both compounds B and C react with DBU in DMF to give disubstituted alkene E. Compound A reacts very slowly with CH3OH to give ether F and a small amount of alkene D. Compound B reacts much faster with CH3OH than compound A to give a different ether G along with alkene D. However, both compounds A and B do not react with strong nucleophiles like NaN3. In contrast, compound C readily reacts with NaN3 in DMF to give compound H. Give the structures of compounds A-H on the next page.
