Question

What is the hybridization state of the central atom in the conjugate base of NH_{4}^{+}NH 4 + ​ ion

Answer 1

So ,in ammonium cation the 'N' -atom formed 4 sigma bond with the four 'H'-atom . Therefore, the hybridization of NH4+ is sp3 . After N atom loses one of its electrons, one s and three p orbitals undergoes hybridisation.
