Answer 1

Epimers:-The two stereoisomer differ in configuration at only one stereogenic center, other stereocenters in the molecules are identical to each other.

Enantiomers:-The two stereoisomer that are mirror images of each other.

Anomers:-Anomers are cyclic monosaccharides that are epimers ,differing in the configuration of C1 carbon in case of aldose or C2 in the case of ketose.

Meso structures:- mesomer is non optically active structure in the pair of stereoisomers because of the presence of sigma plane in the compound that renders the compound optically inactive.

structurutal isomers have the same chemical formula but have different atomic organisation .For example butane and isobutane.

The above question the answer is Epimer.
