Summary
-
1.
The lengths of C-H bonds in allene and ethylene and of C-C bonds in ethylene were calculated.
-
2.
The π -electron charges of C-C bonds in anthracene, triphenylene, and ovalene were calculated. A comparison was made with Scherr's calculations.
-
3.
It was shown that, when a nitrogen atom forms a bond with an atom-donor ofπ -electrons, the free pair of electrons almost always passes, wholly or partially, into the bond and increases itsπ -electron charge.
-
4.
A table is given of π -electron charges in organic compounds.
-
5.
A discussion is given of various hypotheses which have been advanced for the explanation of the regularities observed in interatomic distances.
