Question

why do boron halides occur in monomeric species​

Answer 1

Answer:   Halides of boron exist only in monomeric form because boron atom is too small to coordinate with large halide ions. The energy released during the formation of the bridge structure is not sufficient for the cleavage of the typical p π − p π p\pi- p\pi pπ−pπ bond in B X 3 BX_3 BX3.
