There will be two lone (unbonded) pairs of electrons. This will result in a "t-shaped," weakly polar molecule. The central bromine atom will experience an expanded valence level of electrons, due to its ability to access the 4d energy sublevel. This particle-level property is called hypervalency.
There are two lone pairs on the central atom of bromine in bromine trifluoride, as bromine has 7 valence electrons and forms 3 single covalent bonds with fluorine atoms, leaving 2 lone pairs.

What is the hybridisation state of central atom in nh3 and bf3?
The central atom of ammonia is nitrogen and it has 3 bonding pairs and a lone pair around, hence it undergoes sp3 hybridization. The central atom of boron trifluoride is the boron atom, and around it has only three bonding pairs. So it hybridizes as sp2.
What is the Preferred geometry of molecule BrF3?
The preferred geometry of BrF3 is T-shaped, with the bromine atom at the center and three fluorine atoms arranged around it. This molecular geometry is determined by the repulsion between the lone pair on the bromine atom and the bonding pairs of electrons.
What is the number of nonbonding electron pairs on the central atom of NH2Cl?
The central atom in NH2Cl is nitrogen. Nitrogen has 2 nonbonding electron pairs.
How many lone pairs of electrons does nitrogen triflouride have?
Nitrogen trifluoride (NF3) has one lone pair of electrons on the nitrogen atom.
What is the number of lone pairs around the central atom and the molecular geometry of scl2?
angular with 109.5 degree
What is the steric number of BrF3 central atom?
The steric number of the central bromine atom in BrF3 is 5. This is because BrF3 has 3 bonded fluorine atoms and 2 lone pairs on the bromine atom, giving a total of 5 electron domains around the central atom.
What is the oxidation number of bromine in bromine trifluoride?
The oxidation number of bromine in bromine trifluoride is +3. This is because each fluorine atom has an oxidation number of -1, and since there are three fluorine atoms in bromine trifluoride, the overall charge must balance out to zero.
What is the hybridisation state of central atom in nh3 and bf3?
The central atom of ammonia is nitrogen and it has 3 bonding pairs and a lone pair around, hence it undergoes sp3 hybridization. The central atom of boron trifluoride is the boron atom, and around it has only three bonding pairs. So it hybridizes as sp2.
What is the Preferred geometry of molecule BrF3?
The preferred geometry of BrF3 is T-shaped, with the bromine atom at the center and three fluorine atoms arranged around it. This molecular geometry is determined by the repulsion between the lone pair on the bromine atom and the bonding pairs of electrons.
What is the molecular formula for bromine trifluoride?
The molecular formula for bromine trifluoride is BrF3. It consists of one bromine atom and three fluorine atoms.
What is the hybridization on the central atom in BrO2-?
The central atom in BrO2- has sp3 hybridization. There are two sigma bonds and two lone pairs around the central bromine atom, leading to a tetrahedral geometry and sp3 hybridization.
How many lone pairs are there in hydongen bromide?
The lone pairs are on the bromine atom- 3 in all.
What is the bond between bromine and bromine?
Bromine forms a nonpolar covalent bond with another bromine atom. The bond is formed by sharing of electron pairs between the two atoms.
How is the structure of boron trifluoride?
Boron trifluoride has a trigonal planar structure, with the boron atom at the center and three fluorine atoms surrounding it in a flat, triangular arrangement. The molecule has a total of four electron pairs around the boron atom, including three bonding pairs and one lone pair.
What is the Lewis dot structure for phosphorus trifluoride?
The Lewis dot structure for phosphorus trifluoride (PF3) consists of a central phosphorus atom with three fluorine atoms attached to it. The phosphorus atom has 5 valence electrons, and each fluorine atom contributes one valence electron. There are three lone pairs on the phosphorus atom.
In a tetrahedral molecule how many unshared pairs of valence electrons does the central atom have?
In a tetrahedral molecule, the central atom has 0 unshared pairs of valence electrons. The central atom forms four chemical bonds with surrounding atoms, resulting in a total of 4 electron pairs around the central atom.
How many lone pairs does SF6 have on central atom?
SF6 has no lone pairs on the central atom sulfur. It forms six bonds with fluorine atoms which gives it an octahedral geometry.
