Anyone knows this?

Question

condensed structural formula for,
cis-5-iodo-2-hexene and
2-methyl-3,4,6,trichloroaniline

Answer 1

It's been a while since I took organic, but from what I can remember, 'cis' indicates that the both the attachments will be on the same side of the parent chain... (cis as opposed to trans enantiomer or diasteriomer, which would be on the opposite side - re-read the section on stereo chemistry to be sure).

This is a 6-carbon chain (hex)... the 2 and the "ene" means there is a double-bond at the second carbon (hexane: c-c-c-c-c-c, 2-hexene: c-c=c-c-c-c).

So plop an iodo group onto the 5th carbon and you get something like (had to "draw" this vertically, tilt it 90 degrees)

c
|
c
||
c
|
c

c-I <----- iodine
|
c

to "draw" the cis vs. trans orientation, you'll have to use that weird shorthand (this won't look right here but you'll get the idea... turn 90 degrees again)

cis:
/
||
|
-(I)
\

(trans would be something like:)
\

|
-(I)

For the other one, make your parent chain and stick a methyl group (CH3) on the second carbon, and then a chlorine onto the 3rd, 4th, and 6th carbon.

Answer 2

try this book...."organic chemistry" 6-8th edition by syllianco.

Answer 3

y you getting other ppl to do your homework?

Answer 4

"Anyone knows this?" ........ this title just screams "anyone want to do my homework for me?"

Answer 5

no
