Acetals Hemiacetals Ketals HemiketalsOrganic
Jun 18 2019 · 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
