Question

• Ethane-1,2-diol on reaction with
acidified potassium dichromate results in
the formation of
Answer
A. Formaldehyde
B. Formic acid
C. Acetaldehyde
D. Acetone​

Answer 1

Answer:

option c is the correct answer

Answer 2

When Ethane-1,2-diol reacts with acidified potassium dichromate results in the formation of Formic acid.

• Potassium Dichromate is an oxidizing agent.
• It oxidizes alcohol to aldehyde and then to carboxylic acid.
• The oxidation of Ethane-1,2-diol does not stop after the formation of aldehyde.
• The aldehyde is again oxidized to form a carboxylic acid.

Hence, Ethane-1,2-diol on reaction with acidified potassium dichromate results in the formation of (b) Formic acid.
