12.56 The SN2 reaction can occur intramolecularly (within the same mol- ecule). What product would you expect from treatment of 4-bromo- butan-1-ol with base?
Homework Answers
Treatment of 4-bromo -butanol with base will give first abstract proton from OH and then oxide ion will attack carbon containg bromide and replace the bromide forming cyclic product tetrahydrofuran.

Determine the correct order of steps that will occur for the possible reaction shown below. To enter your answer use the numbers that are adjacent to the correct descriptions in the correct order. For example, if you felt that 1, followed by 2 and then 3 reflects the correct ordering of reaction steps, then you would enter: 1, 2, 3 for your answer. Do so even if the reaction sequence includes two distinct steps (with two different conditions/reagents)....
