Nylon 5-12 Structure Drawing Tutorial

AI Thread Summary
Nylon 5-12's structure is derived from specific diamines and dicarboxylic acids, similar to other nylon types. The discussion highlights confusion regarding the components of nylon 5-12 compared to nylon 6-10, which uses pentamethylene diamine and sebacic acid. The key diamine for nylon 5-12 is 1,5-pentanediamine, also known as cadaverine, a substance associated with a strong odor due to its role as a decomposition product. The conversation also references nylon 4-10, which uses 1,4-butanediamine (putrescine), further emphasizing the unpleasant associations with these compounds. For more detailed structural information, users are encouraged to revisit the Wikipedia article on nylon and explore additional chemical forums.

Hello,

Can anyone tell me how to draw the structure of nylon 5-12 or what site could help me with this?

Thank you!

Hi Borek,

I did googled and Wiki nylon 5-12, I found the structure for nylon 6-10 and it has pentamethylene diamine and sebacic acid, but I'm confused about both to even know what should be added or removed for nylon 5-12.

Thanks.
 
So you have to reread wiki article, as it precisely and unambiguously explains what these numbers mean.
 
Man, I'd hate to be working in a plant that makes 5-10! The diamine, 1,5-pentanediamine, is also known as cadaverine. Cadaverine is a decomposition product of proteins (and Nylon 5-10, BTW) and smells like cadaver or Casey Anthony's trunk!

Probably not as bad as Nylon 4-10 though. It's diamine is 1,4-butanediamine and is known as putrescine, also derived from the decomposition of proteins and nylon 4-XX.
 

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
