Termini in questo insieme (15)

  • Nitronium Ion
    A highly reactive species with a full positive charge, generated from acids, serving as the key electrophile in aromatic nitration.
  • Electrophilic Aromatic Substitution
    A reaction where an aromatic ring replaces a hydrogen with an electrophile, preserving aromaticity after substitution.
  • Benzene
    An aromatic hydrocarbon ring that acts as a nucleophile, attacking strong electrophiles in substitution reactions.
  • Nitric Acid
    A reagent that, when protonated, forms a water leaving group and helps generate the active nitrating species.
  • Sulfuric Acid
    A strong acid commonly used as a proton donor to activate nitric acid for nitronium ion formation.
  • Sigma Complex
    A resonance-stabilized carbocation intermediate formed after the aromatic ring attacks the electrophile.
  • Resonance
    A stabilizing effect in intermediates where charge and bonding are delocalized across multiple structures.
  • Deprotonation
    A step where a proton is removed from the intermediate, restoring aromaticity and completing substitution.
  • Nitrobenzene
    The aromatic product formed after nitration, featuring a nitro group attached to the benzene ring.
  • Aniline
    An aromatic amine produced by reducing a nitro group on benzene, serving as a key synthetic intermediate.
  • Reduction
    A transformation converting a nitro group to an amino group, often using strong or chemoselective reagents.
  • Lithium Aluminum Hydride
    A powerful reducing agent capable of converting nitro groups to amines efficiently in organic synthesis.
  • Catalytic Hydrogenation
    A process using hydrogen gas and a metal catalyst to reduce nitro groups to amines on aromatic rings.
  • Stannous Chloride
    A chemoselective reducing agent that specifically targets nitro groups for reduction without affecting other groups.
  • Chemoselectivity
    A property of certain reagents to selectively react with one functional group in the presence of others.
