Understanding the Basicity of Amines

What is the primary functional group that comes to mind when considering organic bases?

• Ketones

• Alcohols

• Amines

• Carboxylic acids

In an acid-base reaction involving an amine and water, what does the amine become?

• Neutral

• Deprotonated

• Protonated

• Oxidized

Which factor has the most significant impact on the basicity of an amine?

• Electronegativity

• Hybridization

• Aromaticity

• Resonance

How does aromaticity affect the basicity of an amine?

• Increases basicity

• Decreases basicity

• Has no effect

• Makes it a stronger acid

What is the effect of resonance on the stability of an amine's lone pair?

• No effect

• Decreases stability

• Increases stability

• Makes it more reactive

Which of the following is true about resonance and basicity?

• Resonance makes it a stronger acid

• Resonance decreases basicity

• Resonance has no effect

• Resonance increases basicity

How does hybridization affect the energy of a lone pair in an amine?

• Higher s-character increases energy

• Higher s-character decreases energy

• Higher p-character decreases energy

• Hybridization has no effect

Which hybrid orbital has the highest s-character?

• sp4

• sp3

• sp

• sp2

What is the relationship between s-character and the stability of a lone pair?

• Higher p-character increases stability

• No relationship

• Higher s-character increases stability

• Higher s-character decreases stability

Which factor should be considered last when comparing the basicity of amines?

• Electronegativity

• Aromaticity

• Resonance

• Hybridization
