The reagent used for the conversion of decanol into decanoic acid is

  • A.Tollens's reagent
  • B.Jones reagent
  • C.Grignard reagent
  • D.Fehling's reagent
  • E.DIBAL-H

Answer: B

The reagent is Jones reagent.

Jones reagent, chromium trioxide in aqueous sulphuric acid with acetone, is a strong oxidant that takes a primary alcohol such as decan-1-ol all the way to the carboxylic acid, decanoic acid.

Tollens' and Fehling's reagents oxidise aldehydes, not alcohols. A Grignard reagent is a nucleophile used to make new carbon-carbon bonds, and DIBAL-H is a reducing agent, the opposite of what is needed.
