Question

Treatment of formic acid with concentrated sulfuric acid gives

• A. CO + H2O
• B. CO2 + H2
• C. HCHO + ½ O2
• D. no product (no reaction)

Hint:

The dehydration of formic acid with sulfuric acid produces carbon monoxide (CO) and water (H2O). This reaction is a good example of a dehydration reaction.

Answer 1

The Correct Option is A

Step 1: Understanding the reaction.
When formic acid is treated with concentrated sulfuric acid, it undergoes dehydration to form carbon monoxide (CO) and water.

Step 2: Analyzing the options.
(A) CO + H2O: Correct, formic acid undergoes dehydration to produce carbon monoxide and water.
(B) CO2 + H2: Incorrect, as this is not the product of the reaction.
(C) HCHO + ½ O2: Incorrect, as this is not the correct product of the reaction.
(D) no product (no reaction): Incorrect, a reaction occurs and produces carbon monoxide and water.

Step 3: Conclusion.
The correct answer is (A) CO + H2O.
