RyanJ Posted October 17, 2005 Share Posted October 17, 2005 Organic Compounds - Limit to the C-C chain length? Is there a limit to the longest possible C-C chanin? Would it be possible to make a C-C chain made up of all the Carbon atoms in the universe? Its actually pretty mad when you think about - these chanins can be messive, millions of Carbons lond so my question is, is there an actuall limit to this or cna it just go on and on and on... If it would become unstable at a point then I bet it would have to be a huge number of Carbon atoms anyway! Cheers, Ryan Jones Link to comment Share on other sites More sharing options...
The Thing Posted October 17, 2005 Share Posted October 17, 2005 There are different ways for polymer chains to terminate after it grows (such as the natural process called [math]\beta-hydride[/math] elimination. The termination for polymer chains are quite random during polymerization, and this causes a polymer to be able to have polymer chains of various lengths.

akcapr Posted October 17, 2005 Share Posted October 17, 2005 And also, it was a very thin chain, say only a few hunder atoms wide, then it would be really easy to break mechanically so it probably wouldnt stay toghther as a super long chain.

The Thing Posted October 17, 2005 Share Posted October 17, 2005 I just found this. Organic compounds not only have giant structures but gigantic names to go with them. And I mean GIGANTIC. Look at this word I found in wikisource: http://en.wikisource.org/wiki/Methionylthreonylthreonyl...isoleucine Of course, there are even longer ones. DNA can have WAY more letters in its written form.

I mean thats huge but I can't even imaging how big [acr=Deoxyribonucleic acid]D.N.A[/acr] would be... Cheers, Ryan Jones Link to comment Share on other sites More sharing options...
insane_alien Posted October 20, 2005 Share Posted October 20, 2005 i think is well over a billion letters for DNA Link to comment Share on other sites More sharing options...
woelen Posted October 20, 2005 Share Posted October 20, 2005 There is no theoretical limit on the length of C-C chains. Real-life compounds, such as certain plastics and resins can have chains with lengths of many millions or even billions. The limits are of a practical nature. Every compound, made by humans, even the purest ones, has defects, such as impurities, irregularities in the crystal lattice. This is not different for long polymeric chains and hence in practice, the length is limited. Link to comment Share on other sites More sharing options...

Those defects over a long length can cause the structure to break down - seems logical So there is a limit imposed by nature (Defects) but the actual length of the chain would otherwise have no limits? Right - got it! Thanks all Cheers, Ryan Jones Link to comment Share on other sites More sharing options...
Halash Posted October 20, 2005 Share Posted October 20, 2005 dna is pretty damn long i'm sure as they get into the billions of atoms long, they get pretty brittle. and i imagine if they got a few inches long you could snap one.... but could you???????????? that would be breaking a bond with out a chemical...!!!!!!! but wouldn't that cause a big explosion???????????????????????????????????????????

The Thing Posted October 21, 2005 Share Posted October 21, 2005 IIRC, a single strand of DNA in a human chromosome can reach lengths of some 5 centimeters. Link to comment Share on other sites More sharing options...
akcapr Posted October 21, 2005 Share Posted October 21, 2005 A big explsoin would be from breaking many bonds at the basically the same time. Link to comment Share on other sites More sharing options...
RyanJ Posted October 21, 2005 Author Share Posted October 21, 2005 IIRC, a single strand of DNA in a human chromosome can reach lengths of some 5 centimeters. That big? Thats an impressive length. If you take all those chromosomes from every cell in every person, plant etc. you would have a huge chain! Cheers, Ryan Jones Link to comment Share on other sites More sharing options...
