Chapter 5 Sterioisomerism

Nonsuperimposable

- the object and its mirror image are now different.

Chirality

describes nonsuperimposable images in their mirrors reflection.

Chemists

use cis- trans terminology to describe disubstituted (has two substituent atoms /groups) alkenes, even when the two substituents (connected to the π bond) are different from each other.

Superimposable

- mirror image is identical to the actual object.

Diasterisomers

are stereoisomers that are not mirror images.

compound

When a(n) is nonsuperimposable, chiral mirror images of each other it is an Enantiomers.

chiral center

A(n) - is a tetraheadral carbon holding four different groups.

Achiral

- can superimpose in their mirror image.

Stereoisomers

: Same molecular formula and constitution but different spatial arrangements of atoms.

cis stereoisomer

A(n) has groups all on the same side.

Constitutional Isomers

: Same molecular formula but different constitution order of connectivity of atoms.

Constitutional Isomers

Same molecular formula but different constitution order of connectivity of atoms

Stereoisomers

Same molecular formula and constitution but different spatial arrangements of atoms

Superimposable

mirror image is identical to the actual object

Nonsuperimposable

the object and its mirror image are now different

achiral

can superimpose in their mirror image

A chiral center

is a tetraheadral carbon holding four different groups
