Prefixes for aldehydes and ketones

aldehydes are keto and ketones are oxo

11

Chiral Molecules are optically active

Will rotate plane-polarized light to the same magnitude but in opposite direction of mirror image

Rotating to the right is d and +

Left is l and -

Meso comounds will not rotate light

12

Racemic mixture

when both + and - from above are present in equal concentrations

No optical activity

13

Configurational isomers

stereoisomers with differing molecular connectivity. Conformational isomers are stereoisomers with same molecular connectivity at different points of rotation around a single bond

14

number of stereoisomers in a molecule is 2 to the n where n is the number of chiral carbons

2 to the n lol

15

The bulkiest group will favor equatorial position to reduce nonbonded strain with axial groups in the molecule

For chair conformations

16

Structural isomers (constitutional isomers)

only share molecular formula (different connectivity)

17

Conformational isomers

Same connectivity but differ around spatial arrangement or rotation around single bonds

18

Configurational isomers

Same connectivity but require bond breaking to interconvert

19

Specific rotation equation

[alpha] = alphaobserved/ (c x l)

c is conentration in g/mL and l is path length in dm
