$B^{3+}$

Vedclass · Answer

(C) The $B^{3+}$ ion does not exist in an aqueous solution because the ionization energy required to remove three electrons from Boron is extremely high $(IE_1 + IE_2 + IE_3 = 2425 \ kJ \ mol^{-1})$.Due to its small size and high charge density,the $B^{3+}$ ion would have a very high hydration energy,but the energy required to form the ion is not compensated by the hydration energy.Therefore,Boron typically forms covalent bonds rather than existing as a free $B^{3+}$ ion in water.
