Hint :Ethanol is a type of organic chemical. C₂H₆O is the chemical formula for this basic alcohol. Its formula is CH₃CH₂OH or C₂H₅OH, and it is often abbreviated as EtOH. Ethanol is a colourless, toxic, flammable liquid with a distinctive odour.

Complete Step By Step Answer:
Ethanol is a type of organic chemical. C₂H₆O is the chemical formula for this basic alcohol. Its formula is CH₃CH₂OH or C₂H₅OH, and it is often abbreviated as EtOH. Ethanol is a colourless, toxic, flammable liquid with a distinctive odour.
Acetone has the molecular formula (CH₃)₂CO and is a colourless, volatile, flammable organic solvent. It is the smallest and most basic ketone, also known as propanone or dimethyl ketone. Acetone is commonly used for cleaning in homes, businesses, and laboratories.
Ethanol to Acetone
\[C{H_3}C{H_2}OH\xrightarrow[{Cr{O_3}/Pcc}]{{(O)}}C{H_3}CHO\xrightarrow[{DryEther}]{{C{H_3}MgBr}}C{H_3} - CH(C{H_3}) - OMgBr\xrightarrow{{{H_3}{O^ + }}}C{H_3} - CH(C{H_3}) - OH\xrightarrow{{Cr{O_3}}}C{H_3} - CO - C{H_3}\]
Trioxide of chromium (CrO₃) Chromium trioxide is a strong oxidizer that is insoluble in most organic solvents and explodes when exposed to organic compounds and solvents. Acetone can be safely combined with a chromium trioxide solution in aqueous sulfuric acid (Jones Reagent).
A milder form of chromic acid is pyridinium chlorochromate (PCC). PCC, unlike chromic acid, does not convert aldehydes to carboxylic acids. CrO₃ and pyridine (the Collins reagent) both oxidise primary alcohols to aldehydes in the same way.
Grignard reagents are used to make primary, secondary, and tertiary alcohols from carbonyl compounds. The Grignard reagent, R′MgX, is used to make a primary alcohol by reacting it with formaldehyde. When a Grignard reagent is combined with an aldehyde, a secondary alcohol is formed.
