The oxidation of aryl methyl or cyclo alkyl methyl by the treatment with chromyl chloride to an aldehyde via the formation of esters is known as Etard reaction. The oxidation stops at aldehyde stage because the product of the reaction is acylal, R - CH(OCOCH_3)_2 which is resistance to oxidation with this reagent. The acylal on hydrolysis gives aldehyde. What is the product obtained when ethyl benzene is subjected to Etard reaction ?
