Chirality and Stereochemistry Concepts

What is a key characteristic of a chiral carbon atom?

• It is bonded to three different groups.

• It is bonded to four identical groups.

• It is bonded to four different groups.

• It is bonded to two different groups.

Why is chlorocyclopentane not considered a chiral molecule?

• It has more than one chiral center.

• It has a chiral center but is symmetrical.

• It lacks a chiral center.

• It is superimposable on its mirror image.

What makes bromochlorofluoromethane a chiral molecule?

• It has a chiral center with four different groups.

• It is bonded to four identical atoms.

• It can be superimposed on its mirror image.

• It has a symmetrical structure.

What are enantiomers?

• Molecules that are identical in every way.

• Mirror images that are not superimposable.

• Molecules with the same configuration.

• Molecules with different atoms.

What is the main focus of stereochemistry?

• The study of three-dimensional structures.

• The study of atomic numbers.

• The study of molecular weights.

• The study of chemical reactions.

What distinguishes stereoisomers from constitutional isomers?

• Stereoisomers have the same connectivity but different spatial arrangements.

• Constitutional isomers have different molecular weights.

• Stereoisomers have different atoms.

• Constitutional isomers have the same spatial arrangement.

What is the difference between configuration and conformation?

• Neither involves breaking bonds.

• Conformation involves breaking bonds, configuration does not.

• Configuration involves breaking bonds, conformation does not.

• Both involve breaking bonds.

How can you identify a chiral center in a molecule?

• It is bonded to four different groups.

• It is bonded to two identical groups.

• It is bonded to one different group.

• It is bonded to three identical groups.

What is a characteristic of a molecule with a chiral center?

• It has no mirror image.

• It cannot be superimposed on its mirror image.

• It can be superimposed on its mirror image.

• It is always symmetrical.

What is a common feature of enantiomers?

• They have different molecular formulas.

• They have identical chemical properties.

• They are superimposable.

• They are mirror images with different spatial arrangements.
