Question

When nh3 is treated with hcl state of hybridisation on central nitrogen

Answer 1

Answer:

sp3 hybridized.

Explanation:

Since we know that the NH3 is having a bond angle of 107 degree, and due to the high repulsion to the bond pairs by the lone pairs at the nitrogen makes the angle less than the tetrahedral angle.

We also get that after NH3 reacts with HCl, NH3 forms NH4Cl.

But the (NH4)+ does not has any lone pair at nitrogen so, the ammonium ion is making the geometry of perfect tetrahedral like the CH4 as a result the bond angle is 109.5 degree.

Both NH3 and (NH4)+ are hybridised as sp3.
