Read the following two statements carefully and choose the correct option: Statement I: Ethanol on oxidation with alkaline potassium permanganate gives ethanoic acid. Statement II: Oxidation of ethanol involves the removal of hydrogen atoms and addition of oxygen. Which of the following is correct?
Both statements are correct, but Statement II does not explain Statement I.
Both statements are correct, and Statement II explains Statement I.
Only statement I is correct.
Only statement II is correct. Question ID : 4410091078846 Option 1 ID : 4410094252707 Option 2 ID : 4410094252706 Option 3 ID : 4410094252704 Option 4 ID : 4410094252705 Status : Not Answered Chosen Option : --
Both statements are correct, and Statement II explains Statement I.
Ethanol is oxidized to ethanoic acid using oxidizing agents like alkaline KMnO4тАЛ. This process is defined as an oxidation reaction because it involves the addition of oxygen and the removal of hydrogen from the ethanol molecule.
Ethanol is oxidized to ethanoic acid using oxidizing agents like alkaline KMnO4тАЛ. This process is defined as an oxidation reaction because it involves the addition of oxygen and the removal of hydrogen from the ethanol molecule.
Think of oxidation like adding oxygen to a fire; just as fuel turns to ash when it burns, the alcohol 'burns' chemically into an acid by gaining oxygen atoms.

CH3тАЛCH2тАЛOH+2[O]тЖТCH3тАЛCOOH+H2тАЛO тАФ Oxidation of Ethanol to Ethanoic acid
Alkaline potassium permanganate acts as a strong oxidizing agent. The reaction follows: CH3тАЛCH2тАЛOH+2[O]╬ФAlkaline┬аKMnO4тАЛтАЛCH3тАЛCOOH+H2тАЛO. The removal of two hydrogen atoms from the alpha-carbon (bonded to the hydroxyl group) and the addition of an oxygen atom converts the primary alcohol into a carboxylic acid.
Alkaline KMnO4тАЛ and acidified K2тАЛCr2тАЛO7тАЛ are common laboratory oxidizing agents.
Ethanol is a primary alcohol, which oxidizes in two steps: first to acetaldehyde, then to ethanoic acid.
Oxidation is defined classically as the addition of oxygen or removal of hydrogen.
Provides a reliable method to synthesize carboxylic acids in the laboratory.
Over-oxidation can occur if conditions are not carefully controlled.
Production of acetic acid (vinegar) from ethanol.
Industrial synthesis of chemical intermediates.
Ethanol is an alcohol with the formula C2тАЛH5тАЛOH.
Ethanoic acid, also known as acetic acid, has the formula CH3тАЛCOOH.
B is correct тАФ Both statements describe the oxidation of ethanol correctly, and the definition of oxidation provided in Statement II is the fundamental reason why Statement I occurs.
In organic chemistry, always remember that primary alcohols oxidize to aldehydes and then to carboxylic acids when treated with strong oxidizing agents.
