Cards

Term
Arene
Definition
Aromatic hydrocarbon
Term
Hückel's Rules
Definition
1) Conjugated pi bonds in a planar ring?
2) # of pi electrons = 4n+2, where n is an integer?

Remember: for heteroaromatics, they can be sp2 hybridised and therefore contribute 2 pi electrons
Term
Phenol
Definition
Benzene ring w/ an alcohol sticking out of it
Term
Aniline
Definition
Benzene ring w/ an ammine (NH2) group sticking out of it
Term
Alkane
Definition
Linear geometry, sp3 hybridised, 2n+2 hydrogens where n is the # of carbons
Term
Alkene
Definition
Trigonal planar geometry, sp2 hybridised, 2n hydrogens where n is the # of carbons
Term
Alkyne
Definition
Tetrahedral geometry, sp hybridised, 2n-2 hydrogens where n is the # of carbons
Term
Chirality
Definition
Ability of a molecule to have non-superimposable mirror images: therefore the carbon needs at least 4 different substituents.
Term
Organic Isomers
Definition
Constitutional, Stereoisomers, Enantiomers, Diastereoisomers, Cis (E) vs. Trans (Z)
