Adjacent to
bond
Example:

bond
Why would the structure “want” to be like this?
So it can react with other molecules at the carbon!!
Enantiomers
- Stereoisomers that are superimposable mirror images
- Same formula, same connectivity (same flat structure), but different in 3D
“Handedness” in Chemistry, Chiral - handed
Chiral molecules have an enantiomer
Achiral molecules don’t have enantiomers
Stereoisomers
- Some physical properties (except for optical rotation)
- Different physical properties
Example:

Stereoisomers, but NOT enantiomers
Molecules with < 1 stereogenic carbons…
Number of stereoisomers = 2n
Where n = number of stereogenic C’s
But remember, any molecule has one enantiomer
Some molecules are chiral without a stereogenic C

Rotations - not same as R
Chapter 5 - stereochemistry
Stereoisomers - same formula, same connectivity different in 3D
“Stereogenic” carbons
- SP3 hybridized carbon with 4 different groups attached

Enantiomers: stereoisomers that are non superimposable mirror images
Diastereomers: stereoisomers that are not enantiomers
RPS designation of stereogenic carbons

- Assign “Priority” to each group according to atomic number (increase number = highest priority) of the main atom
- If there a tie, go one molecule out,
Example: both have Cs, but number 2 has “0” after!!
- Rotate molecule to have lowest group in back (as dashed group) rip molecule!!

The SS and RR are enantiomers
How do we know? Draw mirror images
Mirror image of RR:




When mirror image, but is super imposable: not enantiomers

- Connect molecules with arrows 1 → 4. If arrows spin molecules,...
Left = S isomer
Right = R isomer
Example:

Name: S - 3 methyl hexane
**Remember priority is based on next individual atom out, NOT size of group or overall atomic weight of group**

Acknowledging that the double bonded carbons bonded TWICE
How to redraw!! R - isomer!!
- “Hold” the non - wedgeldash group that is NOT the 4th priority
- Rotate until 4th group is at the back

**As long as 4 is in back (dashed line), the direction is based on 1, 2, and 3s order
“R and S” designation only in alkanes over hexane
Chirality without stereogenic C

Compared, are they super imposable? No! Molecule is chiral both have enantiomers

Diastereomers: stereoisomers that are not enantiomers
- Compounds with > 1 stereogenic C, 2n stereoisomers where n = number of stereogenic C’s
Example:


22 = 4 stereoisomers
