Most addition reactions to alkenes follow the mechanism of electrophilic addition.

Most experimentally observed reactions are built up from many elementary reactions that occur in parallel or sequentially.

Most chemical reactions are reversible, that is they can and do run in both directions.

Most enzyme reaction rates are millions of times faster than those of comparable un-catalyzed reactions.

Most Np is produced in nuclear reactions:

Most RNA molecules are linear, single-stranded molecules, but both circular and branched molecules can result from RNA splicing reactions.

Most grand unified theories ( GUTs ) explicitly break the baryon number symmetry, which would account for this discrepancy, typically invoking reactions mediated by very massive X bosons () or massive Higgs bosons ().

Most of the ultraviolet spectrum ( which begins above energies of 3. 1 eV ( 400 nm ) is non-ionizing, but is still biologically hazardous due the ability of single photons of this energy to cause electronic excitation in biological molecules, and thus damage them by means of unwanted reactions.

Most of the ozone that is destroyed is in the lower stratosphere, in contrast to the much smaller ozone depletion through homogeneous gas phase reactions, which occurs primarily in the upper stratosphere.

Most steroidogenic reactions are catalysed by enzymes of the cytochrome P450 family.

Most games produced in the Dallas office were hampered by production delays, missed deadlines, and poor critical reactions ( see Production history below ).

Most Grignard reactions are conducted in ethereal solvents, especially diethyl ether and THF.

Most systems found in nature are not in thermodynamic equilibrium ; for they are changing or can be triggered to change over time, and are continuously and discontinuously subject to flux of matter and energy to and from other systems and to chemical reactions.

Most of these reactions are minor.

Most chemical databases store information on stable molecules but in databases for reactions also intermediates and temporarily created unstable molecules are stored.

Most often of all, the reduction of iodine to iodide is the last step in a series of reactions where the initial reactions are used to convert an unknown amount of the solute ( the substance you want to analyze ) to an equivalent amount of iodine, which may then be titrated.

Most commonly, amination reactions involve the use of the amine as the nucleophile and the organic compound as the electrophile.

Most of the time, Martin did not know who the guest would be, to keep his reactions more spontaneous, according to Hale's book Backstage at the Dean Martin Show.

Further developments in the current century might be said to be the increased recognition that ' Most countertransference reactions are a blend of the two aspects ', personal and diagnostic, which require careful disentanglement in their interaction ; and the possibility that nowadays psychodynamic counsellors use countertransference much more than transference − ' another interesting shift in perspective over the years '.

Most important, fermentation regenerates NAD < sup >+</ sup >, maintaining the NAD < sup >+</ sup > concentration so that additional glycolysis reactions can occur.

Most chemical reactions take more than one elementary step to complete, and a reactive intermediate is a high energy, yet stable, product that only exists in one of the intermediate steps.

Most chemical reactions can be hastened with an accelerant.

* Some polymerisation reactions such as the setting of epoxy resin

Polymer physics is the field of physics that studies polymers, their fluctuations, mechanical properties, as well as the kinetics of reactions involving degradation and polymerisation of polymers and monomers respectively.

Other reactions include, methylation, condensation reactions, polymerisation, halogenation etc.

Examples of such reactions are Ring opening metathesis polymerisation, photo-induced ring opening of cyclobutenes, and nucleophilic ring-opening of epoxides and aziridines.

Beyond the use of CGCs for polymerisation reactions, a number of other transformations catalysed by CGCs ( both of Group 3 and 4 metals ) have been reported from academic laboratories.
