Binary Compound Finder Synthlet
Feel free to play around and theoretically synthesize more than 600 main group binaries using the Synthlet below and so search for corresponding real substances
in the Chemical Thesaurus database &
Calculated/predicted stoichiometric formula = NaF
Calculated/predicted name: Sodium fluoride
Actual binary compounds, from the Chemical Thesaurus database:
|Please understand that just because the Synthlet predicts a compound's stoichiometry and name, it does not mean that the compound always exists, that the common or usual name is always constructed or that there is only one binary compound. While most of the predictions are correct, it is the "incorrect" 10% that makes main group chemistry so interesting!
The Binary Compound Synthlet uses the common or lower valency and electronegativity to predict the stoichiometry of the binary compound. For example, electropositive aluminium (valency = 3) reacts with electronegative oxygen (valency 2) to give aluminium oxide: Al2O3.
The Synthlet uses four rules to to construct the name:
- Both elements the same: Element
- One of the elements is He, Ne, Ar or Kr: No binary forms
- Metal + non-metal and non-metal + non-metal: electropositive element followed by electronegative element: Sodium oxide
- Metal + metal: Binary alloy
- Nature is subtle and the rather simple binary construction logic does make "mistakes", howver, the actual compounds are found in the database and wikipedia searches:
||Li + C gives Li2C2 (lithium acetylide) not the predicted Li4C
||B + C gives B4C not the predicted B4C3
||Li + B gives Li2B3, LiB2 & LiB0.8-1.0, not the predictes Li3B
||Li does not alloy with Na, K Rb or Cs due to its small atimic radius, but it does alloy with Al
| CH4, Methane
||The predicted name is Hydrogen carbide
