The Lewis acidity scale of boron trihalides BX₃ (X=F, C1, Br, I) and character of the boron-halogen bonds have been studied by means of DV-X_m approach. Present results show that the acid strength of boron trihalides increases in the order BF₃<BCl₃<BBr₃<BI₃, in excellent agreement with experiments. Based on boron-halogen bonding character, the valence of boron atom in boron compounds can be considered M equal to five instead of three which seems to be more reasonable.
