Consider the following statements : I. Soaps are sodium or potassium salts of long-chain carboxylic acids. II. The properties of catenation and isomerism in the element carbon are attributed to existence of large number of organic compounds than inorganic compounds. III. Carbon dioxide is acidic but carbon monoxide is neutral molecule. Which of the statements given above are correct?
- A. I and II only
- B. II and III only
- C. I and III only
- D. I, II and III ✓
Correct Answer: D. I, II and III
Explanation
All three statements are correct. Soaps are indeed sodium or potassium salts of long-chain fatty (carboxylic) acids. Catenation and isomerism give rise to the immense variety of organic compounds. CO2 dissolves in water to form carbonic acid (acidic oxide), whereas CO is considered a neutral oxide.
