Answer for Question 1, 2 and 3:

1. Ethylene oxide can be polymerized by addition of a trace of acid and water. Give the mechanism of this reaction. HT ethylene oxide polyethylene oxide 2. The careful cleavage of optically active 2-butyl methyl ether by a limited amount of HBr yields mainly bromomethane and 2-butanol. The alcohol has the same configuration and optical purity as the starting material. Show by means of the reaction mechanism why this is so. Why is the alcohol not inverted? 3. Give a simple chemical test that would distinguish between a. butyl ether and pentanol b. butyl ether and pentanol (different test) C. butyl ether and hexene
