2. Variables Any atom except H

4. Additional options allow for the inclusion or exclusion of certain substance classes.

6. Analyze and Refine

10. Zwitterion Is a compound with acidic and basic groups in the same molecule. Tautomers are organic compounds that are interconvertible by a chemical reaction called tautomerization. This reaction results in the formal migration of a hydrogen atom accompanied by a switch of adjacent conjugated double bonds. “Isomers that are rapidly interconverted” (e.g. keto-enol tautomers)

14. Stereo in answer structure No stereo in answer structure

15. Refine Substances

16. Searching by MF • For addition polymers and most condensation polymers put the molecular formula of the monomers, separated by dots, within brackets and close with an “X” • (C8H8)x for styrene homopolymer • (C8H8 . C5H8)x for styrene-isoprene polymers

17. Results for (C8H8 . C5H8)x
