Explanation / Answer
Question 3:
A) The Williamson synthesis involves
option D is correct
option a is not correct because it forms ethers not epoxides.
option b is not correct becasue it involves SN2 mechanism not Sn1
option c is not correct becasue it involves alkyl halide as substrate not alcohol
option e is not correct becasue it involves only primary or secondary alkyl halides not tertiary alkyl hlides.
B) The addition of alcohol to an alkene is option E is correct
