[" Explain that "alpha" - methyl acetyl acetone undergoes enolization to smaller extent than "],[" acetylacetone "]

a. Write the stable tautomer form the following: b. Explain why alpha methyl acetone enolises to a smaller extent than acetylacetone. c. Why is the (-CH_(2)-) group in acetyl acetone (Me-oversetOoverset(||)C-CH_(2)-oversetO overset(||)C-Me) called active methylene group?

Explain why cation has smaller size than neutral atom.

Acid halides undergo esterification at a faster rate than acids. Explain?

Explain : (a) Ethyl isobutyrate does not undergo Claisen condensation in the presence of NaOEt . Acetyl chloride is hydrolysed rapidly by water, whereas benzoyl chloride is not. ( c) beta- Keto esters are stronger acids than alcohols and esters.

Explain why size of cation is smaller than of the parent atom.

Enolic form of acetyl acetone is stablised due to :

Explain why cation are smaller and anions are larger in radii than their parent atoms?
