1.	Give the structure of the product that would be formed when trans-1-bromo-3-methylcyclobutane undergoes as S_(N)2 reaction with NaI.
Answer» Solution :First, write the formulas for the REACTANTS and IDENTIFY the nucleophile, the substrate, and the leaving group. Then, recognizing that the nucleophile will attack the back side of the substrate carbon atom that BEARS the leaving group. causing an inversion of CONFIGURATION at that carbon, write the structure of the product.
