Question

Instructions: Please print off the exam and take it as usual. When you are finished, take pictures of each page and combine them into one PDF with page 1 first, page 2 second, etc. You should then save the PDF in the format of last name first name Test 2. In my case it would be: Lavey Brian Test 2. Once you have saved the PDF, please log into Canvas and click on the assignments link on the left hand side. You will see an assignment labeled Test 2. Click on the link and upload your test/PDF file to it. Do not e-mail it to me unless you are having technical problems and I say to do so. Also, it would be a good idea to take the pictures in normal resolution rather than super high resolution. Hi Res pictures blow up the file sizes and make the file upload speed very slow. 1. Please name the following compounds. (9 points) NH2 w Br

Answer 1

1) 2,7-Dimethyl-2,6-octadiene (first)
The longest chain is identified which is of 8 carbon skeleton so it is oct. Since there are two double bonds so they must be numbered with lowest no. So they are in 2 and 6 positions. It is named diene. Since there are two methyl groups at 2 and 7 positions. So the overall name of the compound is 2,7-Dimethyl-2,6-octadiene
2) 2,4-Dimethylaniline (middle)
The parent compound is an aniline so it is numbered from the carbon attached with the nitrogen. Then it is numbered through the nearest substituent according to their priority. Since there is two methyl group at 2 and 4 positions so the overall name of the compound is 2,4-Dimethylaniline
3) 1-Bromo-4-ethylbenzene (last)
Since this compound has no such special name so they are numbered as their alphabetic order.
