Describe the Cross aldol condensation .

Discuss aldol condensation.

Describe the following: (i) Acetylation (ii) Cannizzaro reaction (iii) Cross aldol condensation (iv) Decarboxylation

Write an acttivity to prove the process of condensation.

Explain with one example for crossed aldol condensation.

Acetaldehyde undergoes the aldol condensation with dil. NaOH. This is because of the presence of

(A) : Acetaldehyde undergoes the aldol condensation with dil. NaOH. (R) : Acetaldehyde does not contain alpha -hydrogen

(A) : Propionaldehyde undergoes aldol condensation . (R) : Propionaldehyde contains five alpha hydrogen atoms

Among the following compounds, some undergo aldol condensation , some undergo Cannizzaro reaction and the remaining undergo neither aldol condensation nor Cannizzaro reaction . Differentiate them and write the structures of the products of aldol condensation and Cannizzaro reaction. i) Benzaldehyde ii) Cyclohexanone iii) Methanal iv) Benzophenone v) 2- Methylpentanal vi) Butan - 1- ol vii) 2,2 - Dimethylbutanal viii) Phenyl acetaldehyde iv) 1 - Phenylpropanone

Which of the following compounds would undergo aldol condensation, which the Cannizzaro reaction and which neither? Write the structures of the expected products of aldol condensation and Cannizzaro reaction. {:("(i) Methanal"," (ii) 2-Methylpentanal"," (iii) Benzaldehyde"),("(iv) Benzophenone"," (v) Cyclohexanone"," (vi) 1-Phenylpropanone"),("(vii) Phenylacetaldehyde"," (viii) Butan-1-ol"," (ix) 2,2-Dimethylbutanal"):}
