Chemistry - Carbonyl compounds Question with Solution | TestHub

Explanation:  

Asking about the carbonyl that will form the maximum hydrated product .

Concept:

This question is based on nucleophilic addition and stability of hydrated carbonyls.

Solution:  

Rate and extent of hydration of carbonyl compounds depend upon the reactivity of carbonyls and stability of hydrated products by H- bonding.

Formaldehyde (CH₂=O) is overwhelmingly hydrated, with  over 99% existing as its hydrate form because CH₂= O is one of the most reactive carbonyl.
