An active methylene compound is a compound that has the following general structural formula. ... Consequently, active methylene compounds are highly acidic and can be deprotonated, for all practical purposes, irreversibly, using common strong bases, such as the hydroxide ion or alkoxide ions.

Which of the compound has active methylene group?

In the first option we have a cyclohexane ring in which there are two carbonyl groups which are having electron withdrawing nature, thus the methylene in between them is called an active methylene group.

Why is EAA called an active methylene compound?

EAA is an important tool to yield various types of organic reagents. Its importance is based on the presence of active methylene group and the ability of it to undergo ketonic or acidic hydrolysis. Due to the acidic nature of methylene hydrogen, it form salt with sodium ethoxide (base).
