Both `t-`butyl and `(-SO_(3)H)` groups are used as a blocking group in certain synthesis of organic compounds. Which of the following statements are correct?
A. `t-` Butyl group is easily introduced by any of the varitions of the Friedel-Crafts alkylation reacton.
B. t-` Butyl group can be intorduced by using:
I. `Me_(3)C - Cl + AlCl_(3)`
II. `Me_(3)C - OH + BF_(3)`
III.
C. `t-` Butyl group can be easily removed under acidic conditions, beucase of the stability of tert-butyl cations.
D. `t-` Butyl group has advantage over a `(-SO_(3)H)` group as a blocking group, becuase `t-` butyl group activates the ring to further `SE` reaction.
