Options
- A5
- B4
- C6
- D3
Correct answer
A. 5
Step-by-step solution
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 aqueous NaOH , whereas alcohols, aldehydes, amines, and hydrocarbons are not. Let us analyze each compound: (I) Benzaldehyde: It is an aldehyde. It does not have an acidic proton and is insoluble in aqueous NaOH . (II) 1-Naphthol: It is a phenol derivati
