The B–C bond in (HO) 2B–CH3 is stronger than the C–C bond in ethane, because a
hyperconjugation interaction is formed between boryl pπ orbital and C–H bonding orbital of
CH3. The M–B (OH) 2 bond (M= Pd or Pt) is also stronger than the M–CH3 bond, because of
the presence of back-donating interaction between M dπ and boryl pπ orbitals and the
considerably large orbital overlaps between B (OH) 2 sp2 and M valence orbitals. Also, the
M–XH3 bond (X= C, Si, Ge, or Sn) becomes weaker in the order M–SiH3> M–GeH3> M …
