MON455 KNOCK-DOWN TRANSFORMER

Molecular structure model can construct the structural formula of various molecules of inorganic and organic substances in chemistry teaching.
Such as graphite, diamond, sodium chloride, alkanes, alkenes, alkynes, halides, alcohols, phenols, ethers, aldehydes, ketones, carboxylic acids, esters, etc. in middle school teaching materials and stereoisomerism and optical isomerism in university teaching materials and the transformation between them, like dichloroethylene (C2H2)CL2 This model can take various isoforms at the same time
