Question 1

______________ are isomers that differ in spatial arrangement of
atoms.

Answer 1

Stereoisomers

Question 2

A non-superimposable set of two molecules that are mirror images of one another.

Answer 2

mirror-image stereoisomer

Question 3

The word “chiral” was derived from the Greek word for _______, because our hands are a good example of chirality since they are non-superimposable mirror images of each other.

Answer 3

hand

Question 4

Molecules are molecules that are not identical to their mirror images

Answer 4

Chiral molecules

Question 5

A molecule that has a plane of symmetry in any of its possible conformation is identical to its mirror image and is ________.

Answer 5

achiral

Question 6

Usually, lack of plane of symmetry is exhibited by molecules containing a carbon atom bonded to different atoms or group of atoms, such an atom is called a _________________________.

Answer 6

chiral center or stereogenic center

Question 7

These are images that coincide at all points when the images are laid upon each other.

Answer 7

Superimposable mirror image

Question 8

These are image where not all the points coincide when laid upon each other.

Answer 8

Nonsuperimposable mirror image

Answer 9

chiral centers
