Nash reaction mechanism
Witryna90 IONIC REACTIONS 6.22 (a) Reaction (2) because bromide ion is a better leaving group than chloride ion. (b) Reaction (1) because water is a more polar solvent than methanol, and S N1 reactions take place faster in more polar solvents. (c) Reaction (2) because the concentration of the substrate is twice that of reaction (1). WitrynaBenzoic acid and NaOH reaction mechanism. The hydrogen atom in the -OH group of benzoic acid is attacked by the OH - of NaOH to form the H 2 O molecule. Then -OH hroup of benzoic acid is broken and …

WitrynaThe reaction is like SN1. It is NOT SN1 but it is carbocationic character driven. Think of it like this, The strong nucleophile will attack vigorously and will not be selective ie. it will attack the carbon which is easily available to it, the one less hindered. Witryna(17) If the product of the reaction was extracted with dichloromethane, it will be in the spherical flask (Step 12). Carry out c.c.f, in a mobile phase of Hexane-Ethyl Acetate (30-70), placing as reference the raw material, if it is solid determine the p. f, and establish its structure and calculate the performance of the reaction.
