What is this?

HI, I was wandering what is this a formula of? and can anyone show me the two geometrical isomers of this compound. Thanks

anyone?

Maybe give it more than 27 minutes for a reply. Also posting a better title may help in the future. There are a ton of threads titled "What's this." Something more specific like "Drawing of unknown bromine containing compound" or something like that may get you more views.

Check into dibromo alkenes I think. Maybe it will help.

Here is a semi related link.

Thanks and sorry for quick double post. Anyone else got any replies?

A question for school, no doubt.
Googling 'geometrical isomers' will lead you to a very nice wiki page explaining cis/trans isomers, and after reading that it will be a piece of cake to figure it out by yourself.

Its (2E)-1,4-dibromopent-2-ene

I only see four carbons - this would be 1,3-dibromo-1-butene. There isn't enough information in your drawing to determine the orientation across the double bond or the chirality at the 3-carbon position. I presume the various combinations of possibilities at those two sites would give you the possible geometric isomers you are looking for.

can anyone show me a isomer structure of this compound which is not a geometrical isomer?. Thanks

icekila - 27-9-2011 at 07:39

Also what do you get when you mix serine and valine? I know water but I dont know the next one

Mildronate - 27-9-2011 at 09:28

sorry yes its 1,3-dibromo-1-butene, i see to much carbons :D

CH2=CH-CH2-CHBr2 would be an isomer that is not a geometrical isomer. Isomers have the same molecular formula but different structures. Geometrical isomers are types of isomers which have the same connectedness of atoms but different three-dimensional geometries.

Usually, I get a mixture of serine and valine! ;)

Under the appropriate conditions, when you combine amino acids you can form AMIDES

CH2=CH-CH2-CHBr2 thanks but do you know what the actual structure looks likes i cant seem to find it

icekila - 28-9-2011 at 08:59

nevermind about the structure but I have a question "Why do all molecules of a specific protein that is also an enzyme always have exactly the same amino acids in exactly the same order?". Thanks

Bot0nist - 28-9-2011 at 09:56

If you have us do all your homework for you, you wont learn a thing.:P Hit the books my friend!

What Bot0nist said!

But that's what DNA does - it codes for every enzyme that our bodies will produce. The transcription of DNA in a cell links amino acids together one at a time to form an exact replica of the same protein being made in any other cell. The genetic code, at its simplest level, is just a way to determine the order of amino acids linked to form proteins. The proteins carry out all the other functions in the body.

CH2=CH-CH2-CHBr2 what does this structure look like

peach - 30-9-2011 at 09:11


icekila - 1-10-2011 at 06:08

Thanks for the help. I only posted when I am completely stuck. So my question is how do I draw a full structure of C3H9NO and OH NH2 have to be in there aswel

icekila - 1-10-2011 at 07:05

Also how can I attach a OH group to c3h9no?
