Yew Meng Lai,Abdul Razak Ahmad,Chang Da Wannd feeble intermolecular forces. Their reactivities have a thermodynamic origin in that these compounds are markedly unstable with respect to replacement of their boron-boron and boron-hydrogen links by bonds to more electronegative elements. Some thermodynamic data bearing on this are in Tables 4-1 and 4-2.

Associated metal hydrides, alkyls, and aryls,of the present chapter to indicate briefly in what types of compound they occur. These types are too numerous to allow also detailed discussion of their reactions, many of which can, however, be inferred by analogy with those of the boron hydrides described in Chapter 4.

Carboranes,ch the organic groups replace terminal hydrogens of the parent boranes. In none of these does the organic group form an electron deficient bridge between two (or more) boron atoms of the type that is common among alkyl derivatives of the neighbouring more electropositive elements beryllium, magnesium, and aluminium.
