Options
- A. A < C < B < D
- B. A < B < C < D
- C. C < A < D < B
- D. C < A < B < D
Answer
A. A < C < B < D
Step-by-step solution
The polarity of organic compounds depends on the presence of polar bonds and their ability to form hydrogen bonds. Diethyl ether (A) has C-O bonds but lacks hydrogen bonding capabilities, making it the least polar among the given compounds. Acetone (C) contains a highly polar C=O double bond, making it more polar than ethers, but it cannot act as a hydrogen bond donor. Ethanol (B) contains an -OH group, which allows it to form strong intermolecular hydrogen bonds, making it more polar than ketones. Acetic acid (D) contains both a carbonyl group (C=O) and a hydroxyl group (-OH). This allows for extensive hydrogen bonding (often forming dimers), making it the most polar of the given compounds. Therefore, the increasing order of polarity is A Answer: A < C < B < D
