Vedclass · Answer

(A) The reaction between acetone $(CH_3COCH_3)$ and $2-$pentanone $(CH_3COCH_2CH_2CH_3)$ in the presence of dilute $NaOH$ and heating is a cross-aldol condensation reaction.Acetone has two equivalent $\alpha-$hydrogens,while $2-$pentanone has two types of $\alpha-$hydrogens (at $C-1$ and $C-3$).Self-aldol products of acetone and $2-$pentanone can also form.The product shown in option $A$ requires a structure that cannot be derived from the condensation of these two specific ketones under the given conditions,as it would require a different carbon skeleton or starting materials.Therefore,the structure in option $A$ is not formed.

Which one of the following is not formed when acetone reacts with $2-$pentanone in the presence of dilute $NaOH$ followed by heating?
