3 reactions mechanism and want to solve some problems based on this then register yourself on Vedantu and unlock free PDFs of NCERT Solutions, sample problems etc. Theoretical rate constants for the OH+CO→H+CO2 reaction using variational transition state theory on analytical potential energy surfaces. Direct dynamics study on the hydrogen abstraction reaction of CH3CH2F with O(3P).
Experiment 8 The SN2 reaction: Factors affecting Sn2 reaction Introduction SN2 reactions are reactions that are favor a strong nucleophile, good leaving group, and aprotic solvent. Chad describes why SN2 reactions require a Strong Nucleophile and are faster with a less substituted substrate and a Polar Aprotic Solvent. If carbocation is unstable, reaction is SN2 while if carbocation is stable reaction is SN2. Ab initio quantum chemical studies of the reactions of CF3CFHO2 with HO2. Am. Ab initio direct dynamics studies on the reactions of chlorine atom with CH3−nFnCH2OH (n = 1–3). When H – atoms of methyl halide are replaced by bulkier alkyl group , then it is more difficult to form transition state (due to steric hinderance of alkyl groups). So, let's start to understand these terms first. Yue-Meng Ji, Jia-yan Wu, Jing-yao Liu, Ze-sheng Li, Chia-chung Sun.
The use of protic solvents (those, such as water or alcohols, with hydrogen-bond donating capability) decreases the power of the nucleophile, because of strong hydrogen-bond interactions between solvent protons and the reactive lone pairs on the nucleophile. Ab initio direct dynamic study on the reaction Br atoms with CH3Br. Dual-level direct dynamics studies for the reactions of dimethyl ether with hydrogen atom and methyl radical. Laura Masgrau, Àngels González-Lafont, José M. Lluch. Theoretical study on the OH + CH3NHC(O)OCH3 reaction. Reaction of Cl with CF3CH2OCHO: A mechanistic and kinetic study.

2) A more electronegative element holds more tightly its valence electrons, which makes it a weaker nucleophile. Yue-meng Ji, Xiao-lei Zhao, Jing-yao Liu, Ying Wang, Ze-sheng Li. Reaction between methyl chloride and nucleophile OH, reactions complete inversion of the configuration of the substrate takes place.
