ACETALS:
An acetal is a functional group with the connectivity R2C(OR')2, where both R' groups are organic fragments. The central carbon atom has four bonds to it, and is therefore saturated and has tetrahedral geometry.
KETALS:
In organic chemistry, a ketal is a functional group derived from a ketone by replacement of the carbonyl (C=O) group by two alkoxy groups. The IUPAC once declared the term "ketal" obsolete, but later accepted it as a subclass of acetals. Therefore, a ketal can also be defined as "an acetal derived from a ketone."
