Bis(trimethylsilyl)amine (also known as hexamethyldisilazane and HMDS) is an organosilicon compound with the molecular formula [(CH3)3Si]2NH. The molecule is a derivative of ammonia with trimethylsilyl groups in place of two hydrogen atoms. An electron diffraction study shows that silicon-nitrogen bond length (173.5 pm) and Si-N-Si bond angle (125.5°) to be similar to disilazane (in which methyl groups are replaced by hydrogen atoms) suggesting that steric factors are not … Web[N, N′-bis(2-amino-κN-ethyl)ethane-1,2-diamine-κN]chloroplatinum(II) tetracarbonyl(η4-2-methylidenepropane-1,3-diyl)chromium α-(trichloromethyl)-ω-chloropoly(1,4 …

You would use bis-, tris-, and tetrakis- when the ligand already has prefixes like di- and tri- in its name, or if you know for sure it is polydentate (includes bidentate, tridentate, hexadentate or generally anything over monodentate). If you were naming 2 dien ligands, you would write bis (dien ... WebExplanation: The cis-trans definition is unambiguous only when you have two different groups on one of the alkene carbons and the same two groups on the other carbon, as in but-2-ene. Then the two identical methyl groups are either cis or trans to each other, and the two identical hydrogen atoms are either cis or trans to each other. im here singing for you bilibili https://mycannabistrainer.com
