1

structural isomers

same molecular formula
different structure
different name

2

stereoisomers

geometric isomers
cis/trans

3

optical isomers

enantiomers

4

enantiomers

not superimpossible
mirror images

5

diasteromers

different physical properties
different chemical properties

6

enantiomers have

polarized light
same physical properties
MP BP density

7

maximum # of stereoisomers

2^n

n= # chiral carbons

8

equal amounts of enantiomers

racemic mixture
0 degrees

9

stereoisomers have

the same name

10

optical isomers

chiral carbon

11

enantiomer

mirror image
NOT superimposable

12

1 chiral carbon...

same molecule
or
enantiomer

13

2 and chiral
1 identical
1 opposite

diasteromer

14

meso compound

turn 180 degrees, same molecule
2 chiral carbons
AND plane of symmetry

15

enantiomer cannot

not meso
because of plane of symmetry

16

are meso compounds optically active

no

17

compounds with no optical activity

1. no chiral carbon
2. meso compounds
3. racemic mixture (equal mole of enantiomers)
