How nh3 is formed?

However, a chemical reaction also occurs when ammonia dissolves in water. In aqueous solution, ammonia acts as a base, acquiring hydrogen ions from H2O to yield ammonium and hydroxide ions. In contrast, the ammonium ion acts as a weak acid in aqueous solution because it dissociates to form hydrogen ion and ammonia.

Keeping this in view, what is the hybridization of the nitrogen atom?

Nitrogen -sp2 hybridization. Nitrogen will also hybridize sp2 when there are only two atoms bonded to the nitrogen (one single and one double bond). Just as for sp3 nitrogen, a pair of electrons is left on the nitrogen as a lone pair. The resulting geometry is bent with a bond angle of 120 degrees.

Is nitrogen sp3 hybridized?

✓ 4 carbon atoms are sp2 hybridized ? Nitrogen atom is sp3 hybridized because it has three sigma bonds and one lone pair. → Done. Not aromatic. It doesn't follow Huckel's Rule (4 pi electrons) AND not all atoms in the ring have p-orbitals.

What is the hybridization of the central atom in brf5?

Hybridisation of BrF5 is sp3d2 with square pyramidal geometry. You can find it by drawing Lewis dot structure of the molecule with five bonds and one lone pair on the central atom.
