Question

The acidity of hydrogen atom on active methylene group is due to. .
​

Answer 1

Explanation:

Thus hydrogen atom can dissociate to give a stable anion. This same phenomena applies to EAA, the two hydrogen atoms bonded to methylene group become acidic and reactive due to two electron withdrawing functional groups i.e. acetyl and ester attached o methylene carbon.

Answer 2

The hydrogen atoms can separate to give a stable anion.

• This equivalent peculiarities apply to EAA, the two hydrogen atoms attached to the methylene bunch become acidic and reactive because of two-electron pulling out useful gatherings for example acetyl and ester connected o methylene carbon.
• Compounds having a methylene span situated between two in number electron pulling out gatherings, (for example, nitro, carbonyl, or nitrile gatherings) are at times called active methylene compounds.
• Treatment of these with solid bases can frame enolates or carbanions, which are frequently utilized in organic blends.
• Subsequently, active methylene compounds are exceptionally acidic and can be deprotonated, overall, irreversibly, utilizing normal solid bases, like the hydroxide particle or alkoxide particles.
