`BH_(4)^(-)` and `NH_(4)^(-)` ions are isolobal - explain.

Text Solution

Verified by Experts

Since the number of atoms (five) , symmetry properties, approximate energy , shape of the orbitals (`sp^(3)` -hybridised ) and number of electrons (10) are similar in `BH_(4)^(-)` and `NH_(4)^(+)` ions, these are called isolobal.
