Why is the nitrogen trichloride molecule pyramidal shape but boron trichloride molecule trigonal planar?
Nitrogen, has 5 electrons in its outer shell, Boron has only 3.
When Nitrogen Bonds with 3 Chlorine atoms, to become NCl3, it still has 2 electrons left in its outer shell, which form a lone pair. As these could bond to a single proton, (i.e. hydrogen without its electron) they have to be shown in the diagram.
NCl3 therefore has 3 bonds and 1 lone pair, so 4 things to show in the bond diagram. Making it trigonal pyramidal.
However, Boron only has 3 electrons to bond. As these are all used up in the bonds with chlorine, there are only 3 bonding pairs to show in the diagram. Therefore it is trigonal planar.
NCl3 has bond angles of 107 degrees
whereas
BCl3 has bond angles of 120 degrees.
Hope this helps.

What is the molecular geometry of nitrogen tribromide?
The molecular geometry of nitrogen tribromide (NBr3) is trigonal pyramidal. Nitrogen has a lone pair of electrons, causing the three bromine atoms to form a trigonal pyramid around the central nitrogen atom.
What is the ammonia molecular shape?
The shape would be pyramidal because of the lone pair nitrogen has
What is the bond type for nitrogen trifluoride?
Its a polar bond, for the electrons are more pulled towards the fluorines. It is a trigonal planar molecule. Sp2 hybridization. Hope this helped.
What is molecular structure of ammonia?
Ammonia molecule is Pyramidal because nitrogen in ammonia has 3 bond pairs and one lone pair of electrons, due to presence of lone pair the H-N-H bond angle is about 107 degree less than normal tetrahedral angle 109.5 degree.
What does the formula NH3 tell you about each molecule of ammonia?
The formula NH3 tells us that each molecule of ammonia consists of one nitrogen atom covalently bonded to three hydrogen atoms. This indicates that ammonia is a polar molecule with a trigonal pyramidal shape due to the lone pair on the nitrogen atom.
What is the molecular geometry or shape of phosphorus trichloride (PCl3)?
The molecular geometry of phosphorus trichloride (PCl3) is trigonal pyramidal. This means that the phosphorus atom is bonded to three chlorine atoms, with the lone pair of electrons creating a pyramidal shape.
What is the molecular geometry or shape of phosphorus trichloride?
The phosphorus trichloride (PCl3) has a molecule with a trigonal pyramidal form.
What is the shape of phosphorus trichloride?
Trigonal pyramidal. Think of the phosphorus as being at the peak of a pyramid and the three chlorides forming the three corners of the pyramis base.
What is the molecular shape of NClO2?
An NCl3 molecule would be a trigonal pyramidal because it has one center N atom with 3 Cl surrounding it, but also a lone pair of electrons on the top which bends the molecule downward, forming a trigonal pyramidal. Its electron shape would be tetrahedral, that is when you count the lone pairs of electrons as bonds themselves.
What shape is ammonia molecule NH3?
Ammonia has a lone pair.Its shape is trigonal pyramidal.
Shape of NF3?
NF3, or nitrogen trifluoride, is a pyramidal molecule with a lone pair of electrons on the nitrogen atom. This lone pair causes the molecule to have a trigonal pyramidal geometry with bond angles of approximately 107 degrees.
The shape of ammonia molecule?
It is Triangular pyramid It would be a trigonal pyramidal.
The shape of the ammonia molecule NH3 is?
The shape of the ammonia molecule NH3 is trigonal pyramidal, with the nitrogen atom at the apex and the three hydrogen atoms forming a triangular base.
What is the shape of the molecule of nbr3?
The molecule NBr3 has a trigonal pyramidal shape. It consists of a central nitrogen atom bonded to three bromine atoms, with one lone pair of electrons on the nitrogen atom. The lone pair causes the shape to be pyramidal rather than planar.
Is CH2NH2 linear or trigonal pyramidal?
CH2NH2 is trigonal pyramidal. It has a central nitrogen atom with three bonded atoms and one lone pair, resulting in a trigonal pyramidal geometry.
Why does ammonia has a pyramidal shape?
Ammonia (NH3) has a pyramidal shape because of its sp3 hybridization. The lone pair of electrons on the nitrogen atom repels the bonding pairs, causing the molecule to adopt a trigonal pyramidal geometry.
What is the molecular geometry of nitrogen tribromide?
The molecular geometry of nitrogen tribromide (NBr3) is trigonal pyramidal. Nitrogen has a lone pair of electrons, causing the three bromine atoms to form a trigonal pyramid around the central nitrogen atom.
