What is the Old Nobby Molecular Kit This Molecular Model Kit has a link remover which makes is very easy to build models for Organic and Inorganic Chemistry models. Molecular Model sets are a useful means for studies in general and organic chemistry. They help with visualising and understanding molecular structures and bonding. Simple modeling activities that can be carried out and then extended to more complex examples include - Saturated organic compounds (all single covalent bonds) - Unsaturated organic compounds (double or triple covalent bonds present) - Cyclic organic compounds - Observing shapes of molecules It is a great set for both students and teachers to aid in course studies!
