To solve this problem, we need to identify the intermediate compound 'X' in the given reaction.$\\$The reaction involves the oxidation of toluene using $$CrO$_2$Cl$_2$ in $$CS$_2. \\$This is a typical example of the Etard reaction, which converts toluene to benzaldehyde.$\\$The reaction proceeds as follows:$\\$1. Toluene reacts with $$CrO$_2$Cl$_2$ to form a chromium complex.$\\$2. The intermediate complex is a dichloro chromium ester of toluene.$\\$3. Hydrolysis of this complex leads to the formation of benzaldehyde.$\\$The structure of the intermediate compound 'X' is:$\\$• A benzyl group attached to a chromium complex.$\\$The correct structure for 'X' is given in Option 1:$\\$• $$CH(OCrOHCl$_2)_2$ attached to the benzene ring.$\\$Therefore, the correct option is Option 1.
