Answer 1

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

C) Ethers are cleaved by acid, base and heat.
