Web1 dec. 2024 · The terms ‘acetal’ and ‘ketal’ have had varied use over the years. Back in the day, acetals were diethers of geminal diols (ie. 1,1-diols), with a formula R 2 C (OR’) 2 ( R’ ≠ H ) where at least one R = H, and were therefore derived from aldehydes. Whereas, when neither R = H, they were called ketals and were obviously derived ...
