The incorrect statement regarding aldol condensation isa)It accomplish...
**Explanation:**
The aldol condensation is a reaction in organic chemistry where an enolate ion reacts with a carbonyl compound to form a new carbon-carbon bond. This reaction is commonly used to synthesize β-hydroxy carbonyl compounds, which can then be further transformed into various functional groups.
Let's analyze each statement to determine the incorrect one:
**a) It accomplishes the formation of a new CC bond:**
This statement is correct. The aldol condensation involves the formation of a new carbon-carbon bond between the α-carbon of the carbonyl compound and the carbonyl carbon of another molecule.
**b) The enolate is favored at equilibrium:**
This statement is incorrect. In the aldol condensation, the formation of the enolate ion is the rate-determining step, but it is not favored at equilibrium. The enolate ion is a relatively strong base and can react further with another carbonyl compound to form a dimer or undergo dehydration to form an α,β-unsaturated carbonyl compound.
**c) The key step in the mechanism of base-catalyzed reaction is the attack of the α-carbon of an enolate ion on the carbonyl carbon:**
This statement is correct. In base-catalyzed aldol condensation, the enolate ion acts as a nucleophile and attacks the carbonyl carbon of another molecule. This leads to the formation of a new carbon-carbon bond.
**d) Dehydration of aldol gives α,β-unsaturated carbonyl compound:**
This statement is correct. The dehydration of the aldol product leads to the removal of a water molecule and the formation of an α,β-unsaturated carbonyl compound. This occurs via an E1cB mechanism, where the β-hydroxy group acts as a leaving group, resulting in the formation of a double bond between the α and β carbons.
Therefore, the incorrect statement is **b) The enolate is favored at equilibrium**. The enolate is not favored at equilibrium, but rather reacts further or undergoes dehydration to form different compounds.
