2-Methylpropan-1-ol is oxidised under Swern conditions (DMSO, (COCl)X2, then EtX3N, −78∘C). The product is
A2-methylpropanal
B2-methylpropanoic acid
C2-methylpropan-2-ol
Dbutan-2-one
Answer: A
The Swern oxidation is a mild, non-aqueous oxidation which converts primary alcohols into aldehydes without over-oxidation. 2-Methylpropan-1-ol gives 2-methylpropanal, (CHX3)X2CH−CHO.
