Which is planar nh3

There is one lone pair of electrons in one of the sp 3 hybrid orbitals of nitrogen. The lone pair—bond pair repulsion distorts the bond angle. Hence, the structure of NH 3 is distorted and it has pyramidal geometry. Report Error Is there an error in this question or solution? Chapter 5: Chemical Bonding - Exercises [Page 79].

It is a polar molecule and is highly associated because of strong intermolecular hydrogen bonding. 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. If there is one lone pair of electrons and three bond pairs the resulting molecular geometry is trigonal pyramidal e. If there are two bond pairs and two lone pairs of electrons the molecular geometry is angular or bent e.

Draw a Lewis structure for the molecule: PF3 has 26 valence electrons. PCl3 has sp3-hybridised phosphorus, with one lone pair. Therefore, molecule has pyramidal shape like ammonia.
