How to convert ethane to propanone?
Alkane to Ketone or Aldehyde:
An alkane can be converted to an alkyl halide through radical halogenation. The alkyl halide can undergo substitution reaction with NaOH to give an alcohol. The alcohol can be oxidized to a ketone or aldehyde.
Answer and Explanation:
The steps needed to convert ethane to propanone are given below.
Step 1: Radical bromination of ethane gives bromoethane.
Step 2: Substitution reaction between bromoethane and NaOH gives ethanol.
Step 3: Partial oxidation of ethanol using the mils oxidizing agent pyridinium chlorochromate (PCC) gives ethanal.
Step 4: Grignard reaction between ethanal and methyl magnesium bromide followed by acidic workup gives 2-propanol.
Step 5: Oxidation of 2-propanol gives propanone.
