Midterm Quiz in Organic Chemistry

This compound has two or more chiral centers but is optically inactive due to an internal plane of symmetry.

Two compounds that differ in configuration at some but not all chiral centers.

A molecule is said to be chiral if it lacks this specific type of symmetry element.

In a Newman projection, this conformation places the two largest substituents 180° apart.

Used in R/S configuration assignment, this rule gives higher priority to atoms with higher atomic numbers.

Isomers that are interconverted by rotation around a single bond without breaking any bonds.

This representation method uses a vertical carbon backbone and assumes horizontal bonds are coming out of the plane.

Used to visualize molecules in staggered and eclipsed conformations, especially ethane.

A compound that rotates plane-polarized light to the left.

An atom that is the source of multiple stereoisomers upon group interchanges but is not necessarily a chiral center.
