What is the point group of NH3?

trans- [PtCl 2 (NH 3 )] contains a C 2 main rotation axis, two orthogonal C 2 axes and three ? v planes. It also has an inversion centre. Hence it belongs to the D 2h point group. This representation ignores the orientation of hydrogen on ammonia.

What is the valency of NH3?

The formula of ammonia NH3 and it is a compound. Its valency is 0 as it follows the Octet rule that is 5 + 3 = 8 electrons in the outermost orbit. Its oxidation number is equal to zero, which means it is a very stable compound, it does not lose or gain any more electrons. In terms of ammonium ion, its valency is +1.

What would the hybridization of NH3 be?

What is the hybridization of nitrogen in ammonia nh3 )? The nitrogen atom in NH3 is sp3 hybridized. If we consider the Lewis structure of ammonia, the four electron pairs around the nitrogen atom require a tetrahedral arrangement. The tetrahedral set of sp3 is obtained by combining the 2s and three 2p orbitals.

What is the full name of NH3?

The name of the compound NH3 is ammonia, other names are azane, tri hydrido nitrogen, nitrogen trihydride. It is a colourless gas with a characteristic pungent smell, it is alkaline in nature. Its molar mass is 17 g/mol, melting point is -77 degree Celcius, the boiling point is - 33 degree Celcius.
