I also had a really bad habit of drawing cyclo - whatever, even when it wasn't in the name. I then like to look at the end of the name and work backwards, so for example, 3,3-dimethyl cyclo pentene... Pent - 5, ene - a double bond (at the beginning because there isn't a number for it), cyclo - I close the pentene, and finish by adding two methyls on Carbon #3. If you just take your time, read the problem carefully, and apply all of the little things that give the compound its name, you can't go wrong.

For some reason I would get into drawing cyclo molecules when it was not even mentioned during the first few days of class. I guess I just thought benzene rings and cycloalkanes looked cool! One thing that I learned was to underline each part. I’ll show you what I mean:<br />a) 3,3-dimethyl cyclo pentene<br />b) 6-bromo 2,3-dimethyl 2-hexene<br />c) ethy vinyl ether<br />d) allyl alcohol<br />One thing that can lead to a mistake is if you don’t read carefully. Knowing your groups is essential but attention to detail is key. A and B I think is the only one that would have been trickily if you did not see the –ene and you were on the Final where your mind was not just focusing on alkenes. <br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-9110535642392948297.post-28233702217308329982013-12-09T11:57:49.835-05:002013-12-09T11:57:49.835-05:00This comment has been removed by the author.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-9110535642392948297.post-27479487434962618502013-12-08T16:14:38.298-05:002013-12-08T16:14:38.298-05:00Before reading you explanation, I tried drawing th...Before reading you explanation, I tried drawing these structures for practice. I found that I need more practice than I thought I did. I had forgotten what Vinyl and Allyl meant and this was the kind of thing I was unlikely to focus studying because I thought I knew everything. So thank you for the reminder!Alex Hunterhttps://www.blogger.com/profile/00973838249924611023noreply@blogger.com
