What is the final product when Benzyl alcohol reacts with two moles of nascent oxygen in the presence of potassium dichromate in acidic medium?

Benzoic acid 

The correct answer is option 2. Benzoic acid.

When benzyl alcohol (\(\text{C}_6\text{H}_5\text{CH}_2\text{OH}\)) reacts with two moles of nascent oxygen (\(\text{O}_2\)) in the presence of potassium dichromate (K2Cr2O7) in acidic medium, the final product formed is benzoic acid (\(\text{C}_6\text{H}_5\text{COOH}\)).

Here is the oxidation process:

Oxidation to Benzoic Acid:

Benzyl alcohol is oxidized by nascent oxygen (\(\text{O}_2\)) provided by the potassium dichromate. Potassium dichromate \((K_2Cr_2O_7)\) acts as an oxidizing agent under acidic conditions, converting the alcohol group (\(-\text{CH}_2\text{OH}\)) of benzyl alcohol into a carboxylic acid group (\(-\text{COOH}\)).  This oxidation step results in the formation of benzoic acid as the final product.

Under the described conditions, benzyl alcohol reacts with nascent oxygen in the presence of potassium dichromate in acidic medium to yield benzoic acid as the final product.
