Vedclass · Answer

(D) The reaction involves the nucleophilic attack of the Grignard reagent $(CH_3MgCl)$ on the carbonyl carbon of the cyclopentanone derivative. The methyl group can attack the carbonyl carbon from either the top or the bottom face of the planar carbonyl group. Since the two methyl groups on the ring are on the same side (cis-configuration),the approach of the $CH_3^-$ nucleophile is not equally hindered from both sides due to the steric effect of the existing methyl groups. However,in such reactions,both stereoisomers (where $-OH$ is cis or trans to the methyl groups) are typically formed as a mixture. The question asks for the product $NOT$ obtained. Since both stereoisomers are formed,all options provided as potential products are actually obtained. Therefore,the correct answer is that none of the listed products are 'not obtained'.

The product$(s)$ not obtained in the following reaction is:
