The current paper describes the effects caused by uniaxial tension of a graphene molecule in the course of the mechanochemical reaction. Basing on the molecular theory of graphene, the effects are attributed to both mechanical loading and chemical modification of the edge atoms of the molecule. The mechanical behavior is shown to be not only highly anisotropic with respect to the direction of the load application, but greatly dependent on the chemical modification of the molecule edge atoms, thus revealing the topological character of the graphene deformation.

Keywords: graphene, molecular theory, electron correlation, mechanochemical reaction; chemical modification; strength characteristics, Young’s moduli.
