`CH_(3)COOC_(2)H_(5`with excess of `C_(2)H_(5)MgBr` and hydrolysis gives

Options

A. `CH_(3)-underset(C_(2)H_(5))underset(|)(C)=0`
B. `CH_(3)-underset(C_(2)H_(5))underset(|)overset(C_(2)H_(5))overset(|)(C)-OH`
C. `CH_(3)-underset(CH_(3))underset(|)C=0`
D. `CH_(3)-underset(CH_(3))underset(|)overset(C_(2)H_(5))overset(|)(C)=0`

Answer

B

Explanation

`CH_(3)-overset(O)overset(||)underset("Ester")(C)-OC_(2)H_(5)+C_(2)H_(5)NgBrto`
`Ch_(3)-underset(C_(2)H_(5))underset(|)overset(OC_(2)H_(5))overset(|)(c)-ONgBroverset(-Mg(OC_(2)H_(5))Br)toCH_(3)-underset(C_(2)H_(5))underset(|)C=0`
`overset(C_(2)H_(5)MgBr)toCH_(3)-underset(C_(2)H_(5))underset(|)overset(C_(2)H_(5))overset(|)(C)-OMgBroverset(-Mh(OH)Br)underset(H.OH)to`
