24 Benzaldehyde can be obtained from benzal chloride. Write reactions for obtaining benzal chloride and then benzaldehyde from it.
It is the commercial method for preparing benzaldehyde. Benzal chloride can be obtained by photochlorination of toluene i.e., chlorination of toluene in presence of sunlight. Then, benzal chloride on heating with boiling water produces benzaldehyde as shown below.
Name the electrophile produced in the reaction of benzene with benzoyl chloride in the presence of anhydrous $\mathrm{AlCl}_3$. Name the reaction also.
Benzene, on reaction with benzoyl chloride undergo formation of benzophenone through intermediate benzoylinium cation.
This is an example of Friedel-Craft acylation reaction.
Oxidation of ketones involves carbon-carbon bond cleavage. Name the products formed on oxidation of 2, 5-dimethylhexan-3-one.
