2. a. Both concentrated sulfuric acid and concentrated phosphoric acid are known to catalyze the conversion of cyclohexanol to cyclohexene via dehydration reaction. Concentrated hydrochloric acid, however, is not a viable option. Provide two reasons on what make sulfuric acid and phosphoric acid advantageous over hydrochloric acid. Look up additional information on these acids if needed. b. In preparation of the bromohydrin (trans-2-bromo-1-methylcyclohexanol) with bromine, side products dibromides shown below are often observed. This side reaction can be essentially avoided...
