Which type of amines would react with Heinsberg reagent to differentiate between primary, secondary, and tertiary amines?

In the synthesis of ethers using the Williamson method, what is the key reagent involved?

In the context of carbocations, what determines the order of stability?

What type of alkyl halides are suitable for SN2 reactions?

Which solvent is suitable for SN2 reactions?

In an SN1 reaction, the solvent is typically:

Which of the following is NOT a requirement for a compound to be considered an aromatic compound?

What is the defining characteristic of a chiral carbon?

Which functional group is considered a strong activating group in electrophilic aromatic substitution reactions?

What is the defining characteristic of enantiomers?

Which type of isomers have molecules that are not mirror images of each other?

What type of directing effect do weak deactivating groups exhibit in electrophilic aromatic substitution reactions?

What kind of reaction do aromatic compounds typically undergo?

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.

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

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.

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

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

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.

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.
