an (aq) ammonium chloride solution, rather than H2SO4, is used in the hydrolsis of the magnesium complex of 1,1-diphenylethanol to ensure that no acid catalyed dehydration occurs. write the chemical structure of the dehydration product from 1,1-diphenylethanol?

-so isnt the structure just 1,1diphenylethanol because there is no hydrolsis

Actually, the use of an (aq) ammonium chloride solution instead of H2SO4 in the hydrolysis reaction is meant to prevent acid-catalyzed dehydration, which typically occurs when a strong acid is present. In this case, you are correct that no dehydration product will be formed.

The structure of 1,1-diphenylethanol remains unchanged during hydrolysis in an (aq) ammonium chloride solution. Therefore, the chemical structure of the product would still be 1,1-diphenylethanol. No further reactions, such as dehydration, take place due to the absence of a strong acid catalyst.
