Question

Boron does not form B^3+ ion. Why?

Answer 1

As the first ionization energy for Boron is very high hence the total enery required to produce B^3+ ions is much more than would be compensated by lattice energies of ionic compounds or by hydration energy of B^3+ ions in the solution. As a result boron can not form B^3+ ions.............

$\huge\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\purple{R}}}}$

❤⭐ :REASON:⭐❤

• ❤.. Due to $\red{\tt{Non}}$_$\purple{\tt{availability}}$ of$\orange{\tt{d}}$ orbitals,boran is unable to expand its$\green{\tt{Octet}}$.
• ❤...Therefore,the maximum cobalence of boran cannot exceed4.
