C.chem

Test your knowledge of organic chemistry nomenclature. 6 levels — early high school up to university — each with 3 difficulty levels.

Randomly generated structural formulas across 6 levels (early high school up to university), each with 3 difficulty levels. Excellent practice material for any pupil or student studying chemistry. The breakdown and content of the levels: Lvl 1: alkanes and simple alkenes Lvl 2: Lvl 1 + more alkenes, simple branching, alcohols Lvl 3: Lvl 2 + acids, amines, halogens Lvl 4: Lvl 3 + alkynes, benzene and cyclic compounds (middle high school) Lvl 5: Lvl 4 + cis/trans isomerism, recognizing asymmetric carbon atoms, thiols, aldehydes, ketones, nitro compounds, etc. (late high school) Lvl 6: Lvl 5 + E/Z and R/S nomenclature, simple heterocyclic compounds (college, university)
