Molymod Molecular Orbital Organic Structures Set

This set consists of sufficient parts to make models of benzene, ethane, ethene and ethyne. The atom cores are represented by the standard Molymod? atom parts, and the atomic and molecular orbital parts by colour-coded, matt or pastel-coloured pieces. These exclusively designed models help to demonstrate both sigma-bonding and pi-bonding and therefore the concept of electron delocalisation and orbital hybridisation.

Atoms:

• 2 x carbon (6 holes)
• 8 x carbon (5 holes)
• 2 x carbon (4 holes)
• 18 x hydrogen (1 hole)

Bonds:

• 9 x carbon-carbon (oval shaped) sigma-bonds
• 18 x carbon-hydrogen (pear shaped) sigma-bonds
• 9 x pi-bonds (21 pink and 21 purple pieces).
