[amp_mcq option1=”Acetylene” option2=”Methyl alcohol” option3=”Methane” option4=”Ethyl formate” correct=”option4″]
The correct answer is: D. Ethyl formate
When formaldehyde and potassium hydroxide are heated, they react to form ethyl formate, a colorless liquid with a pleasant fruity odor. It is used as a solvent, a flavoring agent, and a fragrance.
The reaction is as follows:
$$\ce{HCHO + KOH -> CH3COOCH2CH3 + H2O}$$
Acetylene (A) is a colorless gas with a garlic-like odor. It is used as a fuel and a chemical intermediate.
