dimithyle cyclohexabenzene to as a Reagent HCl and hit what would be find?
Answers
Answer:
The products are probably i) benzaldehyde ethyl hemiacetal and ii) 2,2-dichlorobutanal hydrate.
i). Benzaldehyde + ethanol
This reaction appears to be a the formation of a hemiacetal.
Alcohols undergo acid-catalyzed addition to aldehydes to form hemiacetals.

ii) 2,2-Dichlorobutanal + water
Aldehydes undergo addition of water to form hydrates.
The reaction is catalyzed by acid and is greatly enhanced by electron withdrawing groups adjacent to the carbonyl group.
