conformational isomerism identification

Functional ISOMERISM

In the given conformation C2 is rotated about C2–C3 bond anticlockwise by an angle of 120° then the conformation obtained is :A Fully eclipsed conformation  B Partially eclipsed conformation C Gauche conformation  D Staggered conformation

Which term can be used to classify the relationship between two isomers that have the same connectivity but specific rotations of +40° and −25°, respectively?A.EnantiomersB.Racemic mixtureC.DiastereomersD.Conformational isomersSubmit
