Clustering reactions

 +  = ( • )

By formula: C^- + C = (C^- • C)

( • ) +  = ( • 2)

By formula: (C^- • C) + C = (C^- • 2C)

( • 2) +  = ( • 3)

By formula: (C^- • 2C) + C = (C^- • 3C)

( • 3) +  = ( • 4)

By formula: (C^- • 3C) + C = (C^- • 4C)

( • 4) +  = ( • 5)

By formula: (C^- • 4C) + C = (C^- • 5C)

( • 5) +  = ( • 6)

By formula: (C^- • 5C) + C = (C^- • 6C)

( • 6) +  = ( • 7)

By formula: (C^- • 6C) + C = (C^- • 7C)

( • 7) +  = ( • 8)

By formula: (C^- • 7C) + C = (C^- • 8C)

( • 8) +  = ( • 9)

By formula: (C^- • 8C) + C = (C^- • 9C)
