The chirality degrees of planar bezenoids were suggested on the basis of weighed atomic sums which are the descriptions of atomic asymmetric environments related to the distance between atoms. The chirality of compounds was quantitatively measured, rather than labeled as chiral or achiral. The enantiomers could be distinguished from each other and the values of their chirality measurements take opposite number. The chirality degrees could be a multi-dimensional vector or a single value to represent chirality of compounds. The three dimensional structures of n-alkane rotamers could be transformed into 2D benzenoids, then the chirality degree also could be used to describe the 3D conformers.

Key words: benzenoid, binary code, weighed atomic sum, chirality degree, rotamer
