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?
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?
Options
- AI and II only
- BII and III only
- CI and III only
- DI, II and III
Correct answer
D. I, II and III
Step-by-step solution
Statement I is correct as soaps are sodium or potassium salts of long-chain fatty acids, which are carboxylic acids.
Statement II is correct as the unique properties of carbon, such as catenation (the ability to form long chains and rings) and isomerism, are responsible for the vast number of organic compounds compared to inorganic compounds.
Statement III is correct as carbon dioxide (CO_2) is a neutral oxide.
Thus, all statements I, II, and III are correct.
Statement II is correct as the unique properties of carbon, such as catenation (the ability to form long chains and rings) and isomerism, are responsible for the vast number of organic compounds compared to inorganic compounds.
Statement III is correct as carbon dioxide (CO_2) is a neutral oxide.
Thus, all statements I, II, and III are correct.
