CHX3CHX2MgBr is added to propanone and the mixture is hydrolysed with HX3OX+. The product is
Apentan-2-ol
B3-methylbutan-2-ol
C2-methylbutan-2-ol
Dbutan-2-ol
Answer: C
Ethyl adds to the carbonyl carbon of (CHX3)X2C=O to give (CHX3)X2C(OMgBr)CHX2CHX3. Hydrolysis gives the tertiary alcohol (CHX3)X2C(OH)CHX2CHX3, 2-methylbutan-2-ol.
