2. Chemicals are identified in multiple ways. Ethylenediamine could also be listed as:
1,2-Ethanediamine OR 107-15-3 OR C2H8N2
3. Chemistry related reference materials include dictionaries, encyclopedias, handbooks, and methods. To learn more about a topic in broad details, you would start with an encyclopedia but to find a specific data point, you would start with handbook.
4. Have an isomer? Each could have their own CAS registry number.
