;(ii) Jones reagent;(iii) 
;(ii) Jones reagent;(iii) B
(i) 
;(ii) NaOEt ;(iii) Jones reagent
;(ii) NaOEt ;(iii) Jones reagent C
(i) Jones reagent;(ii) NaOEt ;(iii) 
D
(i) NaOEt;(ii) 
;(iii) Jones reagent
;(iii) Jones reagent
Text Solution
Verified by ExpertsThe correct answer is:
D
The transformation of 
benzene with Br and 
substituents to 
benzene with 
requires:
First, NaOEt causes elimination of HBr to form an alkene intermediate.
Second, 
performs hydroboration-oxidation, adding hydroxyl group in anti-Markovnikov fashion to yield a primary alcohol.
Third, Jones reagent oxidizes the primary alcohol to carboxylic acid.
The sequence 
Jones reagent produces the desired carboxylic acid product.
