  2. Reaction mechanism - Wikipedia

    en.wikipedia.org/wiki/Reaction_mechanism

    Consider the following reaction for example: CO + NO 2 → CO 2 + NO. In this case, experiments have determined that this reaction takes place according to the rate law = []. This form suggests that the rate-determining step is a reaction between two molecules of NO 2. A possible mechanism for the overall reaction that explains the rate law is:

    For example, in the CAS scheme "group VIIB" denotes manganese group (group 7), while in the old IUPAC scheme it denotes halogen group (group 17). If they are used at all, context should clarify (disambiguate) into the 1–18 numbering. Care should be taken when translating old sources that use this nomenclature to modern terminology.

    In 2020, it was announced that Google's AlphaFold, a neural network based on DeepMind artificial intelligence, is capable of predicting a protein's final shape based solely on its amino-acid chain with an accuracy of around 90% on a test sample of proteins used by the team.

    Because the S 2− anion has a subscript of 2 in the formula (giving a 4− charge), the compound must be balanced with a 4+ charge on the Pb cation (lead can form cations with a 4+ or a 2+ charge). Thus, the compound is made of one Pb 4+ cation to every two S 2− anions, the compound is balanced, and its name is written as lead(IV) sulfide.

    Lorazepam can be made using 2-amino-2′,5-dichlorobenzophenone (a derivative of 2-amino-5-chlorobenzophenone), which is first reacted with hydroxylamine, the obtained product is then reacted with chloroacetyl chloride to give 6-chloro-2-chlormethyl-4-(2′-chlorophenyl)quinazolin-3-oxide, a reaction with methylamine produces ring expansion and rearrangement, which forms 7-chloro-2-methylamino ...

  9. List of chemical classifications - Wikipedia

    en.wikipedia.org/wiki/List_of_chemical...

    Chemical classification systems attempt to classify elements or compounds according to certain chemical functional or structural properties. Whereas the structural properties are largely intrinsic, functional properties and the derived classifications depend to a certain degree on the type of chemical interaction partners on which the function is exerted.
