Final answer:
The molecular geometry of NH4+ is tetrahedral.
Step-by-step explanation:
The molecular geometry of NH4+ is tetrahedral.
There are four bonds between the nitrogen atom and hydrogen atoms, with no lone pairs present. The four regions of high electron density arrange themselves to point to the corners of a tetrahedron, with the central nitrogen atom in the middle. N H 4 + has tetrahedral molecular geometry and the bond angle is 109.5 . c. Polarity: In ammonium ion, the polarity of N-H bonds is canceled out because, all those 4 hydrogens in ammonium ion are bonded symmetrically to the central atom nitrogen, which results in a nonpolar ammonium ion.
Therefore, the electron pair geometry of NH4+ is tetrahedral, and the molecular structure is also tetrahedral.
