JEE Mains · Chemistry · STD 12 - 8.2 Carboxylic acids and their derivative
Amongst the following, the total number of compounds soluble in aqueous \(NaOH\) at room temperature is:
- A \(5\)
- B \(4\)
- C \(6\)
- D \(3\)
Answer & Solution
Correct Answer
(A) \(5\)
Step-by-step Solution
Detailed explanation
To determine which compounds are soluble in aqueous \(NaOH\), we need to identify the compounds that are sufficiently acidic to react with \(NaOH\) (a strong base) to form water-soluble sodium salts. Generally, carboxylic acids and phenols are acidic enough to dissolve in…
