In case of dihalide like problem 8.54 c. 1. my think is like this. at the first E2 reaction, the hydrogen on cyclohexyl will be participate because its carbon is more substituted. then second E2 reaction, there are no more hydrogen on left carbon. so hydrogen on right carbon will be partcipate. as a result, the product is double bond not triple bond. Why is this wrong and only form triple bond? 2. Is it impossible to make Sn2 reaction that NH2- is working as nucleophile?
