Question

56. A Claisen condensation involves formation of ..
A. Oxygen-oxygen
B. Carbon-oxygen
C. Carbon-hydrogen
D. Carbon-carbon
​

Answer 1

Answer:

D. Carbon Carbon

Explanation:

The Claisen condensation is a carbon–carbon bond forming reaction that occurs between two esters or one ester and another carbonyl compound in the presence of a strong base, resulting in a β-keto ester or a β-diketone.

Answer 2

Answer:

D. Carbon - Carbon

Explanation:

The Claisen condensation is a carbon–carbon bond forming reaction that occurs between two esters or one ester and another carbonyl compound in the presence of a strong base, resulting in a β-keto ester or a β-diketone. It is named after Rainer Ludwig Claisen, who first published his work on the reaction in 1887.
