Aldol condensation takes place in the presence of _ ?
Correct answer: C. NaOH
- A. H2SO4
- B. K2Cr207
- C. NaOH
- D. H20/H+
Explanation
Option C is correct since the aldol reaction happens in aldehydes and ketones if the compounds contain no less than one α-hydrogen. Therefore, the reaction occurs in the presence of alkali (dilute). The dilute alkali acts as a catalyst in the reaction and helps in the formation of β-hydroxy aldehydes or aldol and β-hydroxy ketones or ketol.

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
