Document Summary

Acid catalyzed ring opening of epoxides: epoxides more reactiive than dialky ethers b/c of large strain, epoixdes react in both basic & acidic conditions. In water: acid catalyzed hydrolysis of epoxides gives gylcerols with anti sterochemistry. Inolves protonation of oxygen followed by sn2 attack by water. It produces an alkocy alchohol with anti steiochemistry: used to make compounds with ether with alcohol functional group. Base-cataylzed ring opening of epoxides: ethers do(cid:374)"t u(cid:374)dergo (cid:374)u(cid:272)leophil(cid:272) su(cid:271)sttu or eli(cid:373)iatio(cid:374) u(cid:374)(cid:272)der (cid:271)asi(cid:272) conditions b. c alkodix is poor leaving group, strain in epoxides allows for subs or elim, epoxides are hugher in energy than ether. Epoxides displacement has lower energy: alkocide ions react with epoxides to form ring-opend products, amines can open epoxides. Rxn of epoxide with grignard & organolithum reagents: grignard & organolithim reagents attack epoxides to give ring- opened alcohols. Cleavage of ethers by hbr & hi: alcohols are reactive. Iodine and bromide ions are good nucleuphiles but weak base.

Paper Specifications:

The writing component is minimally a five-page single space paper in size 12 font. The paper is expected to be written clearly and be free of grammatical mistakes in either the APA or IEEE format. The paper must include:

An abstract that gives a clear, concise description of the paper in less than 100 words. â¨

At least two pages that serve as an introduction to topic being discussed. Included in this introduction should be precise definitions and examples to help clarify any new concepts. The audience for this paper will be your peers, so make sure you write at an appropriate level. â¨

A few problems/examples completed and clearly written up. Make sure that you work a number of your own examples and don't just follow examples provided in your sources. The solutions need not be shown in there entirely, but must include a few key steps as well as an explanation of what the computation means. â¨

At least one additional (and interesting) application or example of this topic that was not found within the textbook. Be sure to cite youâre outside source using APA or IEEE style in your paper. â¨

A work cited page in either APA or IEEE style that is absence of questionable/inappropriate sources. â¨
