Clustering reactions

C₂H₆NO₂⁺ +  = (C₂H₆NO₂⁺ • )

By formula: C₂H₆NO₂⁺ + C₂H₅NO₂ = (C₂H₆NO₂⁺ • C₂H₅NO₂)

C₂H₆NO₂⁺ +  = (C₂H₆NO₂⁺ • )

By formula: C₂H₆NO₂⁺ + H₂O = (C₂H₆NO₂⁺ • H₂O)

Bond type: Hydrogen bond (positive ion to hydride)

Free energy of reaction

(C₂H₆NO₂⁺ • ) +  = (C₂H₆NO₂⁺ • 2)

By formula: (C₂H₆NO₂⁺ • H₂O) + H₂O = (C₂H₆NO₂⁺ • 2H₂O)

Bond type: Hydrogen bond (positive ion to hydride)

Free energy of reaction

(C₂H₆NO₂⁺ • 2) +  = (C₂H₆NO₂⁺ • 3)

By formula: (C₂H₆NO₂⁺ • 2H₂O) + H₂O = (C₂H₆NO₂⁺ • 3H₂O)

Bond type: Hydrogen bond (positive ion to hydride)
