{'ethanol reacts': [0, 0, 1, 0], 'acetic acid': [0, 0, 0, 1], 'potassium dichromate': [0, 0, 1, 0], 'citric acid': [0, 0, 1, 0], 'folic acid': [0, 0, 1, 0], 'malic acid': [1, 0, 2, 0]}

When ethanol reacts with potassium dichromate, the correct answer is option 1: Acetic acid.

Potassium dichromate is a strong oxidizing agent, and when it reacts with ethanol (CH3CH2OH), it oxidizes the alcohol group (OH) into a carbonyl group (C=O). This process is known as oxidation of ethanol.

The reaction can be represented as follows:

CH3CH2OH + K2Cr2O7 + H2SO4 [REPLACEMENT] CH3COOH + Cr2(SO4)3 + K2SO4 + H2O

In this reaction, ethanol is converted into acetic acid (CH3COOH). Acetic acid is a simple organic acid with the chemical formula CH3COOH. It is commonly found in vinegar and has a sour taste.

It is important to note that the other options provided in the question – citric acid, folic acid, and malic acid – are not produced when ethanol reacts with potassium dichromate. These options are different organic acids and are not formed in this specific reaction.

Therefore, the correct answer is option 1: Acetic acid.
