Understanding Isomerism

What distinguishes structural isomers from each other?

• Different phases of matter

• Different types of atoms

• Different connectivity of atoms

• Different molecular formulas

Which of the following is true about enantiomers?

• They have different molecular formulas.

• They are mirror images of each other.

• They have different connectivity.

• They are identical in every way.

What happens when all chiral centers in a molecule are inverted?

• An enantiomer is formed.

• The molecule becomes achiral.

• A structural isomer is formed.

• A diastereomer is formed.

In cis-trans isomerism, what is the main difference between the isomers?

• The molecular formula

• The spatial arrangement of substituents

• The type of atoms

• The number of atoms

Which type of isomerism involves substituents being on the same or opposite sides of a cyclic molecule?

• Cis-trans isomerism

• Enantiomerism

• Structural isomerism

• Functional isomerism
