Isomerism And Intermolecular Forces Flashcards
When naming an element what is the stem/parent for?
Shows the number of carbon atoms in longest chain bearing the functional group
When naming an element what is the suffix for
The ending tells u which functional group is present
(If necessary, the position is annotated -2-)
When naming an element what is the prefix for?
If necessary, a prefix for showing the position and identify of any substituents
-side-chain names appear in alphabetical order
-if identical side-chains appear more than one prefix with di,tri,tetra etc
Name the structural isomerisms
Chain
Position
Functional
Name the stereoisomerisms
Geometric
Optical
Outline chain isomerisms
Different arrangement of a molecules carbon skeleton
Outline position isomerism
The differing position of the same functional group in the molecule
Outline functional group isomerism
Differing positions of atoms give a different functional group
Outline geometric isomerism
Different substituents around a bond with restricted rotation
What is a cis stereoisomer
Substituents on same side of double bond
What is a trans stereoisomer
Substituents on opposite sides of double bond
Outline optical isomers
Non-superimposable mirror images of the same molecule
Outline enantomers
Stereoisomers, molecules with the same connectivity, but different spatial orientation
Differ in their arrangement at positions called chiral centres
Mirror image of each other
What is an atoms electro negativity affected by
It’s atomic number and the size of the atom
What is a dipole
A bond or molecule whose ends have opposite charges
