This kit enables users to build virtually all simple molecules encountered in organic chemistry. Includes space-filling models that simulate the true shape of saturated compounds. Provides open models that form realistic single, double, and triple bonds even strained rings. Allows smooth rotation of the bonds to make conformational analysis easy. Contains enough components to create several models at once. The components are precision-tooled from quality plastics, are virtually indestructible, and come in a sturdy plastic case for easy storage. Provides a useful Instruction Book with photos, diagrams, and concise discussions of chemical principles.Pearson Education is the author of 'Prentice Hall Molecular Model Set For Organic Chemistry', published 1983 under ISBN 9780205081363 and ISBN 0205081363.
