BH3 has three electron pairs around the boron atom, resulting in a trigonal planar molecular geometry due to the repulsion between the electron pairs around the central atom. This geometry allows for the maximum separation between electron pairs, leading to a more stable molecule.

WHY BOND ANGLE DECREASES WHEN WE MOVE FROM NH3 TO BH3?
The bond angle decreases from NH3 to BH3 primarily due to the difference in the presence of lone pairs and the types of bonding orbitals involved. NH3 has a lone pair on nitrogen, which exerts repulsion and pushes the hydrogen atoms closer together, resulting in a bond angle of about 107 degrees. In contrast, BH3 has no lone pairs on boron and adopts a trigonal planar geometry with bond angles of approximately 120 degrees. However, the effective repulsion from the empty p-orbitals in BH3 leads to a slight decrease in bond angle compared to the ideal trigonal planar geometry.
What is the shape of Co32?
CO32- is trigonal planar, bond angles are 1200
Does SO3 have tetrahedral geometry?
No. SO3 (sulfur trixoide) has trigonal planar geometry.
What is the correct molecular shape for no3?
trigonal planar
What is structure of borane?
Borane is a compound with the chemical formula BH3. It has a trigonal planar structure with one boron atom at the center and three hydrogen atoms attached to it. In reality, borane forms stable complexes with various other molecules due to its electron deficiency.
What is the shape of BH3 molecule?
BH3 has a trigonal planar shape with 120 angles.
Which molecule has 120 degrees bond angle?
A trigonal planar molecule such as sulfur trioxide (SO3) or boron trihydride (BH3) has a trigonal planar shape. Trigonal pyramidal molecules such as ammonia (NH3) have bond angle closer to 107 degrees.
What is the electron Geometry of BH3?
The electron geometry of boron trihydride (BH3) is trigonal planar. This is due to the presence of three bonding pairs of electrons around the central boron atom, arranged symmetrically at 120-degree angles. There are no lone pairs on the boron atom, which helps maintain this planar arrangement.

Is N2O- trigonal planar or trigonal pyramidal?
Not linear.
What is the molecular shape of SeO3?
Sulfur tetraoxide is a trigonal planar. There is the sulfur in the middle and three oxygen that surrounds it with all of them a double bond linking them to the sulfur.
What is a trigonal planar?
nh3
What is the hybridization of ion CH3 plus?
This carbocation which only has six electrons is isoelectronic with BH3 and is believed to have a similar structure as gaseous molecular BH3, planar with bond angles of 120 0. The hybridisation would be sp2 with and empty p orbital.
What is the approximate bond angle for a molecule with a trigonal planar shape?
For a truly trigonal planar molecule the bond angles are 120 0 exactly.
Is BH3 polar non polar or ionic?
BH3 is non polar because the bond angles are all 120 degrees and cancel out. I know this one was tricky! think of it this way, BH3 is trigonal planar. The "B" atom is surrounded by 3 "H" atoms. all these H atoms are partially positive. Because if that, the outer part of the molecule is uniformly positive. so another atom "looking at" BH3 would "see" the same charge from all sides of the molecule. it works in the same way for CCL4 and CH4 and other symmetric molecules.
