  2. Solvent effects - Wikipedia

    en.wikipedia.org/wiki/Solvent_effects

    The rate equation for S N 2 reactions are bimolecular being first order in Nucleophile and first order in Reagent. The determining factor when both S N 2 and S N 1 reaction mechanisms are viable is the strength of the Nucleophile. Nuclephilicity and basicity are linked and the more nucleophilic a molecule becomes the greater said nucleophile's ...

  3. Reaction mechanism - Wikipedia

    en.wikipedia.org/wiki/Reaction_mechanism

    An example of a simple chain reaction is the thermal decomposition of acetaldehyde (CH 3 CHO) to methane (CH 4) and carbon monoxide (CO). The experimental reaction order is 3/2, [4] which can be explained by a Rice-Herzfeld mechanism. [5] This reaction mechanism for acetaldehyde has 4 steps with rate equations for each step :

  4. Molecularity - Wikipedia

    en.wikipedia.org/wiki/Molecularity

    The kinetic order of any elementary reaction or reaction step is equal to its molecularity, and the rate equation of an elementary reaction can therefore be determined by inspection, from the molecularity. [1] The kinetic order of a complex (multistep) reaction, however, is not necessarily equal to the number of molecules involved.

  5. Collision theory - Wikipedia

    en.wikipedia.org/wiki/Collision_theory

    The rate for a bimolecular gas-phase reaction, A + B → product, predicted by collision theory is [6] = = ⁡ ()where: k is the rate constant in units of (number of molecules) −1 ⋅s −1 ⋅m 3.

  6. SN2 reaction - Wikipedia

    en.wikipedia.org/wiki/SN2_reaction

    The bimolecular nucleophilic substitution (S N 2) is a type of reaction mechanism that is common in organic chemistry. In the S N 2 reaction, a strong nucleophile forms a new bond to an sp 3 -hybridised carbon atom via a backside attack, all while the leaving group detaches from the reaction center in a concerted (i.e. simultaneous) fashion.

  7. Blue bottle experiment - Wikipedia

    en.wikipedia.org/wiki/Blue_bottle_experiment

    The aqueous solution in the classical reaction contains glucose, sodium hydroxide and methylene blue. [14] In the first step an acyloin of glucose is formed. The next step is a redox reaction of the acyloin with methylene blue in which the glucose is oxidized to diketone in alkaline solution [6] and methylene blue is reduced to colorless leucomethylene blue.

  8. Click chemistry - Wikipedia

    en.wikipedia.org/wiki/Click_chemistry

    For a reaction to be considered a click reaction, it must satisfy certain characteristics: [5] modularity; insensitivity to solvent parameters; high chemical yields; insensitivity towards oxygen and water; regiospecificity and stereospecificity; a large thermodynamic driving force (>20 kcal/mol) to favor a reaction with a single reaction ...

  9. Finkelstein reaction - Wikipedia

    en.wikipedia.org/wiki/Finkelstein_reaction

    The classic Finkelstein reaction entails the conversion of an alkyl chloride or an alkyl bromide to an alkyl iodide by treatment with a solution of sodium iodide in acetone. Sodium iodide is soluble in acetone while sodium chloride and sodium bromide are not; [ 3 ] therefore, the reaction is driven toward products by mass action due to the ...
