240 Pcs Organic Chemistry Molecular Model Student and Teacher Kit Student and Teacher Kit Include 86 Atoms 153 Bonds 1 Short Link Remover Tool Instructional Guide

?? Build Larger Molecules The atom is the cornerstone of life, and we will never have enough atoms. That's why we design our molecular set to cover the foundations of chemistry while also building more complex molecules. This group is suitable for displaying functional groups, bonding, VSEPR and molecular conformation on a larger scale. As we expand our chemistry knowledge and fun, we can do better! ?? What's in the box? This molecular model kit has a total of 240 pieces, including a link remover. With this set, it is easy to build organic and inorganic chemical models! All parts are made of durable and sturdy plastic in a colour that meets national standards. This is a great help for students and teachers! ?? Durability, Flexibility, and Ease of Use It can be used to formulate the structural formula of various molecules of inorganic and organic substances in chemical textbooks. Such as alkanes, olefins, alkynes, halides, alcohols, phenols, aldehydes, ketones, esters, etc. in the textbooks of secondary schools and stereoisomeric, optical isomerism and transformation between them in university textbooks. Like dichloroethylene (C2H2) Cl2, this model can simultaneously form three isomers. ?
