This application is for students studying organic chemistry, for teachers and organic chemists. There are more than 180 structural formulas. Hydrocarbons are the fundamental class of organic compounds. So it is very important to know their chemical names.
Questions are divided into 6 topics. There are all major classes of hydrocarbons. The database is prepared by a PhD chemist. Begin with basic structures such as methane CH4, benzene C6H6, and isomers of octane C8H18. Then proceed to advanced subjects. Learn about benzopyrene C20H12 and cubane C8H8.

Independent evidence report

Five-star share of ratings
80–89% five-star

In the package we scanned
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence about the app, not a finding about it.
