Organic Introductions Flashcards
Saturated
Contain single carbon-carbon bonds only.
Unsaturated
Contains c=c double bond
Molecular formula
Formula which shows the actual number of each type of atom
Empirical formula
Simplest whole number ratio of each atom in a compound
General formula
Algebraic formula for a homozygous series
Structural formula
Minimal detail that shows the arrangement of atoms in a molecule
Displayed formula
Shows all covalent bonds and atoms present in a molecule
Skeletal formula
Simplified organic formula shown by removing hydrogen atoms from alkyl chains leaving just a skeletal skeleton and associated functional groups
Homozygous series
Families of organic compounds with the same general formula
Homozygous series features are:
Show gradual change in physical properties
Each member differs by one CH2 from the last
Same chemical properties

How do you tell the positions of functional groups?
Count how many carbons go from lowest to highest
Which come first functional groups or branched carbon chains
Functional groups
What happens if there are multiple of the functional group
Di tri tetra penta hexa
General rules for naming carbon chains
Count longest chain
Find any branched and how many carbons they contain
Add appropriate suffixes
Hydrocarbon
Compound made of carbon and hydrogen only
Homolytic fission define
Each atom gets one electron the covalent bond
Half curly arrow
How many radicals does homolytic fission produce?
Two
Free radicals are:
Free radicals (•) don't have charge Reactive species which possess an unpaired electron
Heterolytic fission
One atom gets two electrons

Structural isomers
Same molecular formula different structures (structural formulae)
What can structural isomerism come from?
Chain isomerism
Position isomerism
Functional group isomerisms
Chain isomers are?
Compounds with same molecular formula but different structures carbon skeleton
Position isomerism
Compounds with same molecular formula but different structures due to different positions of the same functional group in the carbon skeleton.
Functional group isomerisms
Compounds with same molecular formula but different functional group
Stereoisomers
Same structural formula but different spatial arrangement of atoms
What isomerisms can alkenes exhibit?
E-Z isomerism
When do E-Z isomerism arise?
Restricted rotation around c=c double bond
Two different groups/atoms attached to both ends of the double bond
Why do E-Z isomers exist?
Restricted rotation about c=c bonds
Do e-z isomerism happen in single bond
No because they can easily rotate
How do determine whether a molecules is E or Z?
Find highest Ar
If largest are on the same side then Z
If largest on both sides then E
