Which of the following compounds will react with sodium hydroxide solution in water?
(i)
(ii)
(iii)
(iv)
The answer is the option(i). Sodium hydroxide is a strong base and to be able to make the reaction feasible; the other acidic reactant should be strong. Option (ii), (iii), and (iv) are alcohols and are weak in nature due to less affinity towards water thus they are able to dissociate into ions only to a certain extent. Whereas option (i) phenol is a strong acid due to its higher affinity towards water. This makes option (i) as the right answer
