The sequence of three steps involved in the following conversion is
(a)(i) Friedel-Crafts alkylation; (ii) Reduction; (iii) Friedel-Crafts acylation
(b)(i) Friedel-Crafts acylation; (ii) Friedel-Crafts alkylation; (iii) Reduction
(c)(i) Friedel-Crafts acylation; (ii) Reduction; (iii) Friedel-Crafts alkylation
(d)(i) Friedel-Crafts alkylation; (ii) Friedel-Crafts acylation; (iii) Reduction
Answer
Answer: B ✓ checked by 4AB · confidence medium
Explanation
Friedel–Crafts acylation (propanoyl) first. The acyl group directs the isopropyl group meta, and Clemmensen/Wolff–Kishner reduction then converts the acyl to propyl, giving the 1,3-product (b).
