In this study, the relationship between some of the topological indices such as diameter, the number of boron, the number of nitrogen in contrast to theelectrical moments such as dipole, octapole quadrupole, hexadecapole electric moments of some chiral polyhex BN nanotubes (BNNT) arepresented. The results are performed by densityfunction theory method with Becke,s 3-parameter formulation by the Lee-Yang-Parr functional (B3LYP) method on 3-21G basis set
