Which of the following statements applies to the E2 mechanism? A) It occurs with inversion of stereochemistry. B) It proceeds through the more stable carbocation intermediate. C) The C-H and C-X bonds that break must be trans. Use of a bulky base gives the more highly substituted alkene product. E) It occurs with racemization of stereochemistry. D)

Please, make the answer clear
and reable.
BrEtOH a OEt Hace H2C Alkyl halides undergo nucleophilic substitution and elimination reactions. When the kinetics of the reaction are measured, if the rate of the reaction is found to be dependent only upon the concentration of the alkyl halide the reaction is first order. The substitution reaction is thus termed ction is termed E1. These reactions are unimolecular and occur in two steps. The first step is rate-limiting and involves the loss...

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...
