Organic Chem Flashcards
Organic molecules contain…
Both carbon and hydrogen
Only carbon and hydrogen=
Hydrocarbon
What is catenation?
Chemical linkage of chains of atoms
Carbon
Ethane has-
Single bond
Saturated
Ethene has-
Double bond
Unsaturated
No information on structure and bonding in molecular but can be demonstrated in structural.
Structural formula
Preferred to show complex structures
Skeletal formula
Share the same general molecular formula
Contain same chemical properties
Show trend in physical properties
Homologues Series
Chain isomers
Same molecular formula but different carbon chain.
Can exhibit different chemical and physical properties
Structural isomer
Belong to same homologues series with the functional group attached to different carbon atoms
Functional group isomers
Same molecular formula but different functional group
Stereoisomers
Same molecular and structural formula but different orientation
Chiral carbon
Middle carbon in stereoisomer
Enantiomers
Two optical isomers
Active substances that rotate the plane of polarised light either clockwise or anti-clockwise
Optical isomers
