need help with 14-21 Stereochemistry of the Su2 reaction In the Sn2 reaction the tetrahedral carbon center is inverted. We describe the mechanism as nudeophilic (Nuc) back side attack; the leaving group (LG) is leav ing from the front side. Generally, the LG and the Nucare electron rich so it would be unfavorable for them to react from the same side (charge repuls ion). The geometry of the carbon at the transition state is trigonal planar. 14) Label the 2-bromobuta...
Jame: . Complete this mechanism for the following substitution reaction. Note: this reaction is balanced. H-Br Н,0 OH -CH3 H20 Step 1: proton transfer Step 2: lose water Step 3: attack the carbocation Br -CH3 . Each reaction above is reversible. In question 1, what effect would adding more HBr have on the equilibrium? Would there be more or less alkyl bromide product present at equilibrium? . Two dehydrations can occur on glycerol, the principle carrier molecule in vaping devices....
using the picture of the reaction above and the following given experimental data from "Reactions of Butanols with HBr" lab: mass of 1-butanol used=5.35g crude mass extracted (actual yield)=1.70g a) calculate the theoritical yield of the extracted crude mass. b) calculate the %yield of the reaction. please solve it correctly with explanation and I'll provide good rating thank you • CH3CH2 CH2 CH2 OH + HBr Hesen CH3 CH2 CH2 CH2 Br + H2O
