D) Methyl phenylketone
Show Answer
Answer:
Correct Answer: A
Solution:
$ \xrightarrow{-MgBr(OCH_3)}\overset{O}{\mathop{\overset{||}{\mathop{CH_3-C-Ph}}}}\xrightarrow{PhMgBr}\underset{Ph}{\mathop{\underset{|}{\mathop{\overset{OMgBr}{\mathop{\overset{|}{\mathop{CH_3-C-Ph}}}}}}}} $
$ \xrightarrow{{H^{+}}}\underset{\text{1,1-diphenylethanol}}{\mathop{\underset{Ph}{\mathop{\underset{|}{\mathop{\overset{OH}{\mathop{\overset{|}{\mathop{CH_3C-Ph}}}}}}}}}} $
