Alcohols Phenols and Ethers Test - 6

Secondary alcohols are oxidized to ketones. The oxidation of isopropyl alcohol by potassium dichromate (K₂Cr₂O₇) gives acetone, the simplest ketone: Unlike aldehydes, ketones are relatively resistant to further oxidation, so no special precautions are required to isolate them as they form.

C₆H₅OCH₂CH₃ is ethyl phenyl ether or phenetole is an organic compound that is an ether. Ethyl phenyl ether has the same properties as some other ethers, such as volatility, explosive vapors, and the ability to form peroxides.

IUPAC name : Ethoxybenzene

Other names : Phenetole, Ethyl Phenyl Ether

The Grignard Reaction is the addition of an organomagnesium halide (Grignard reagent) to a ketone or aldehyde, to form a tertiary or secondary alcohol, respectively. The reaction with formaldehyde leads to a primary alcohol.

Grignard Reagents are also used in the following important reactions: The addition of an excess of a Grignard reagent to an ester or lactone gives a tertiary alcohol in which two alkyl groups are the same, and the addition of a Grignard reagent to a nitrile produces an unsymmetrical ketone via a metalloimine intermediate.

RCHO + R₁MgX →→ RCH(OH)R₁
