Acetic acid is soluble in;
Correct answer: A. Water, Alcohol, Ether
- A. Water, Alcohol, Ether
- B. HCI, HBr, HI
- C. Bromine water
- D. All of these
Explanation
Acetic acid also known as ethanoic acid (CH3COOH) can form hydrogen bonds with water and alcohol since all three species have OH group. It is also soluble in ethers due to their polar nature.In option B HBr and HI are less polar due to smaller electronegativity difference between hydrogen and bromine/iodine resulting in weaker permanent dipole-permanent dipole interactions between acetic acid and HBr or HI hence acetic acid will not fully dissolve.In option C, some bromine reacts with water to form HBr and HOBr in bromine water. Br2 is a non polar molecule and there will only be weak instantaneous dipole induced dipole forces between Br2 and acetic acid.

About Carboxylic Acids
Carboxylic acids are named and studied through the combined effects of the carbonyl and hydroxyl groups, their preparation, acidity and hydrogen bonding. Reactions include neutralisation, esterification, reduction and conversion into acid chlorides, anhydrides, esters and amides, with emphasis on how these derivatives interconvert.
