Homework Answers
(a) A secondary alcohol on reaction with chromic acid (H2CO4) gives a ketone (D).
(b) The ketone D in presence of H2O and H2SO4 gives a diol (F).
(c) The primary alcohol on reaction with pyridinium chloro chromate (PCC, a mild oxidizing agent) gives an aldehyde (H).
(b) This is a Friedel-Crafts acylation reaction. Since Cl is ortho- para directing group and -COCH3 is meta directing the acyl group added in para position of the
-Cl atom. Hence the product is (B).
