Ester and ether are organic molecules with oxygen atoms. Both have the ether linkage which is âO-. Esters have the group âCOO. One oxygen atom is bonded to carbon with a double bond, and the other oxygen is bonded with a single bond. Since only three atoms are connected to the carbon atom, it has a trigonal planar geometry around it. Further, the carbon atom is sp2 hybridized.
