Chapter 3 - Stereoisomerism and Chirality 

The ________ refers to an object that lacks chirality; an object that has no handedness.

________ are isomers that lack a chiral center yet do not interconvert due to impeded rotation.

The term atropisomers refers to enantiomers that lack a(n) ________ and differ because of hindered rotation.

Because there is a(n) ________ when all four carbons are planar, the anti isomer is achiral.

________ are small things with sizes ranging from few to hundreds of Angstroms, but they have distinct forms and geometries, as covered in the preceding two chapters.

There are ________ in the planar conformer due to the massive groups on the rings, and the twisted forms illustrated have much lower energies.

A(n) ________ is an object's reflection in a mirror.
