Molymod Organic Student Set

Each Organic Chemistry Student Set comes with an instruction leaflet and is packed in a four-compartment box. The Organic Chemistry molecular model Student Sets are designed for school, college or self study (private) chemistry courses. Sufficient links are provided to make single, double, and triple bonds for OPEN and short links for CLOSED models. The models can easily be assembled and reassembled to make hundreds of possible structures.
