On the Hydrides of B, C, N, O and F

I have had thoughts on the hydrides possible for B, C, N, O & F, and particularly for N there seems to be some interesting undiscovered possibilities. Thus I am aware of: (1) the hydrides of B have been investigated & elucidated by Stock et al. and Lipscomb et al. & I have tried to read this literature, but I am not able to get a reliable source, and I understand that the hydrides of B differ from those of C, N, O and F in that they exhibit in some cases exceptions to covalent, electron-pair, 2center bonds, in the form of electron deficient, 3-center bonds, and that there are innumerable hydrides of B, like the innumerable hydrides of C, which in some cases display resonance effects in their hydroboron structures as suggested by Pauling et al., and (2) the hydrides of C are innumerable and they universally possess Lewis octet, covalent, electronpair, 2-center bonds, with rare exceptions in which a hydrocarbon has perhaps C atoms in strained geometries which may possess coordination numbers different than 3 or 4, they are successfully described by Pauling's VB theory and Mulliken's MO theory, and some hydrocarbons display classical quantum mechanical resonance effects as predicted by Pauling et al. including the archetypal system benzene.
