For each of the following reactions, draw the major elimination product; if the product can exist as stereoisomers, indicate which stereoisomer is obtained in greater yield. a. (R)-2-bromohexane + high concentration of CH3O−
b. (R)-3-bromo-3-methylhexane +CH_3OH,
c. trans-1-chloro-2-methylcyclohexane + high concentration of CH_3O^-CH 3O − d. trans-1-chloro-3-methylcyclohexane + high concentration of CH_3O^-,CH3O −
e. 3-bromo-3-methylpentane + high concentration of CH_3CH_2O^-CH3CH 2O−
f. 3-bromo-3-methylpentane +CH_3CH_2OHCH3CH2OH
