How do I know which reaction to use for alcohols, ethers and epoxides? If somebody could please explain,, I would be SO appreciative. We just finished sn1, sn2, e1 and e2 reactions and I understand which reaction to use since we had a chart. No chart this time and I am lost. The reactions include, dehydration, Williamson ether, e1, e2, sn1, sn2 and please let me know if I'm missing anything else. Thank you!
