It is a highly flammable, weakly alkaline, water-miscible liquid with a distinctive, unpleasant fish-like smell. Pyridine is colorless, but older or impure samples can appear yellow, due to the formation of extended, unsaturated polymeric chains, which show significant electrical conductivity.
The amide group can be involved in hydrogen bonding to other nitrogen- and oxygen-containing species.. The predominant solid state form is 2-pyridone. This has been confirmed by X-ray crystallography which shows that the hydrogen in solid state is closer to the nitrogen than to the oxygen (because of the low electron density at the hydrogen the exact positioning is difficult), and IR ...
Skeletal structural formula of Vitamin B 12.Many organic molecules are too complicated to be specified by a molecular formula.. The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are possibly arranged in the real three-dimensional space.
The handling of this chemical may incur notable safety precautions. It is highly recommend that you seek the Material Safety Datasheet for this chemical from a reliable source such as eChemPortal, and follow its directions.
The head of the Transportation Security Administration on Thursday warned that an extended partial U.S. government shutdown could lead to longer wait times at airports. TSA, which handles airport ...
The Atlanta Hawks will be without Larry Nance Jr. for the foreseeable future. The Hawks forward is set to undergo surgery for a broken bone in his right hand later this week, the team said on Monday.
U.S. billionaire Elon Musk's support for Germany's far-right Alternative for Germany (AfD) is a "logical and systematic" play for a weak Europe that will not be able to regulate as strongly, Vice ...
Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.
