Public access ACE pages
ACE Mechanism calculator. Calculate the products of a mechanistic step involving one or more compounds and electron-flow arrows.
ACE Synthesis calculator 1. Calculate the products of a reaction, using one of ACE's predefined reactions.
ACE Synthesis calculator 2. Calculate the products of a reaction, using a reaction you define yourself.
ACE Functional-group finder. Find which functional groups a compound contains.
ACE Rotation about bonds. Designate a particular dihedral angle for a bond in a 3D structure.
ACE Chair flip. Flip to the other chair conformer of a substituted saturated six-membered ring.
ACE Chair or half-chair flip. Flip to the other chair or half-chair conformer of a substituted saturated or monounsaturated six-membered ring. (For saturated compounds, we recommend the ACE Chair flip page instead of this one.)
ACE Stereocenter configuration inversion. Invert the configurations of selected sp3 stereocenters in a 2D or 3D structure, or get the structure's mirror image.
ACE Stereoisomer generation. Convert a compound with unspecified configurations at its stereocenters into all stereoisomers.
ACE Pericyclic mechanism calculator. Determine whether any of the steps of a mechanism with electron-flow arrows are pericyclic.
ACE Hybridization calculator. Find the hybridization of each atom in a compound.
ACE Parity calculator. Find the parity of each atom in a compound.
ACE pKa calculator. Find the pKa of each atom in a compound.
ACE contiguous C atom calculator. Find the largest set of contiguous C atoms in a compound.
JChem® substructure finder. See how JChem® compares two structures.
ACE skeleton comparator. See whether a structure contains a particular skeleton.
ACE conformer comparator. Compare two conformers with ACE.
ACE toDisplay() tester. See how ACE will display an expression that an author types into a question statement or feedback.
