Complete the following reaction

A

`Ph-underset(Ph)underset(|)overset(OH)overset(|)(C)-Ph`

B

`Ph-underset(CH_(3))underset(|)overset(OH)overset(|)(C)-CH_(3)`

C

`Ph-overset(O)overset(||)(C)-CH_(3)`

D

`Ph-overset(O)overset(||)(C)-Ph`

Text Solution

Verified by Experts

The correct Answer is:
B
`{:(" "O" "O" "overset(ɵ)(O)overset(o+)(M)gBr" "OH),(" ||"" ||"" |"" |"),(Ph-C-N-O-CH_(3)overset(CH_(3)MgBr)rarrPh-C-CH_(3)overset(CH_(3)MgBr)rarr Ph-C-CH_(3)overset(H^(o+))rarrPh-C-CH_(3)),(" |"" |"" |"),(" "CH_(3)" "CH_(3)" "CH_(3)):}`
excess of `CH_(3)MgBr` is used to maximise the yield.
