Question:
Amongst those given below, the total number of compounds soluble in aqueous NaOH are:
3
5
6
8
0
7
1
2
4
9
Solution:
The compounds soluble in aqueous NaOH are cyclohexanoic acid, phenol, 4-dimethylaminoethanol, naphthalene-1-carboxylic acid. The solubility is due to the acidity of a carboxylic group or phenolic OH group which react with NaOH to form soluble salts. Thus, the total number of compounds soluble in aqueous NaOH is 4.
