Amines and Reagents

Heinsberg reagent can differentiate between primary and secondary amines; tertiary amines do not react.
In the Williamson synthesis of ethers, the key reagent is an alkoxide ion.

Carbocations

Stability of carbocations is determined by the degree of substitution; tertiary > secondary > primary due to hyperconjugation and inductive effects.

Alkyl Halides and Reactions

SN2 reactions require primary or methyl alkyl halides for successful nucleophilic substitution.
Polar aprotic solvents, such as acetone or DMSO, are suitable for SN2 reactions.

Alcohols and Oxidation

Common reagent used for alcohol oxidation is potassium dichromate or chromium trioxide.

SN1 Reaction

SN1 reactions typically use polar protic solvents like water or alcohols to stabilize the carbocation intermediate.

Aromatic Compounds

A compound is not considered aromatic if it does not meet Huckel's rule, which requires 4n + 2 π electrons, where n is a non-negative integer.
Chiral carbon is defined by having four different substituents attached to it.
Strong activating groups in electrophilic aromatic substitution are groups like -OH, -NH2, or -O-R that increase electron density on the aromatic ring.

Isomers and Stereochemistry

Enantiomers are defined by being non-superimposable mirror images of each other.
Diastereomers are a type of isomer where molecules are not mirror images of each other.
Weak deactivating groups in electrophilic aromatic substitution exhibit a meta-directing effect.

Reactions of Aromatic Compounds

Aromatic compounds typically undergo electrophilic aromatic substitution reactions, allowing the substitution of hydrogen atoms with electrophiles.
