Question

Write the products formed when (CH3)3 C- CHO reacts with the
following reagents :
(i) CH3COCH3, in the presence of dilute NaOH
​

Answer 1

No product will formed when (CH3)3 C- CHO reacts with the following reagents due to:

• Here, the aldol condensation reaction will not occur as for aldol condensation atleast one alpha hydrogen should be there.

• Alpha hydrogen is hydrogen at carbon adjacent to carbonyl carbon. But in (CH3)3 C- CHO it is not present.

• So for this reaction, (CH3)3 C- CHO reacts with reagents CH3COCH3, in the presence of dilute NaOH and it will form no product , let's see the reaction:

dil.NaOH

• (CH3)3 C- CHO + CH3COCH3 —> no reaction.

Answer 2

Answer:

Aldol condensation takes place!

(CH3)3C-CHO does not have alpha hydrogen but CH3COCH3 has alpha H

the product formed is

5,5- dimethyl hex-3-en-2-one
