Ethyl ethanoate is treated with excess CHX3MgBr in dry ether and then with aqueous acid. The organic product other than ethanol is
Apropanone
B2-methylpropan-2-ol
Cbutan-2-ol
Dpropan-2-ol
Answer: B
The first equivalent gives propanone (CHX3COCHX3) after loss of CX2HX5OMgBr. Propanone is more reactive than the ester and takes a second equivalent to give (CHX3)X3C−OMgBr, which on hydrolysis is (CHX3)X3C−OH.
