Esters

I doubt the "ester conformation" part is required:

• The oxygen has 2 nonbonding electron pairs → never a stereocenter. Since it also has 2 (NOT 1) bonding electron pairs, it is also not a center of geometrical isomerism.
• The carbon next to the oxygen has 3 bonds → never a stereocenter, and since it is bonded to another oxygen with a double bond, it is not a center of geometrical isomerism.
