What is the formal charge for BrO2?
The formal charge on bromine in the molecule HBr is -1. There are a number of rules for assigning the formal charge to an atom. The most important of them is that the sum of the formal charges on each atom must equal the charge on the molecule or ion. Since the Br has a formal of -1 and the charge on HBr is zero, then the formal charge on the hydrogen atom must be +1. The bromine atom has a formal charge of -1 because another important rule is that the most electronegative atom will have a negative formal charge equal to the number of electrons it needs to fill all of its outer orbitals. Since bromine has seven electrons, it needs one electron to fill its outer shell.
What kind of covalent bond is HBr?
HBr forms a polar covalent bond, where the hydrogen atom has a partial positive charge and the bromine atom has a partial negative charge due to differences in electronegativity. This results in an uneven sharing of electrons.
How many atoms are in HBr?
There is one hydrogen atom and one bromine atom in one molecule of HBr.
How do you know HBr is polar?
HBr is a polar molecule because it has a significant difference in electronegativity between hydrogen and bromine. Bromine is more electronegative than hydrogen, causing a partial negative charge on the bromine atom and a partial positive charge on the hydrogen atom, creating an overall dipole moment in the molecule.
Is there a hydrogen bonding in HBr?
No, hydrogen bonding does not occur in HBr because it does not have a hydrogen atom bonded to a highly electronegative element like oxygen, nitrogen, or fluorine. Hydrogen bonding requires a hydrogen atom directly bonded to one of these highly electronegative elements.

Hydrogen bromide bond?
Hydrogen bromide (HBr) forms a polar covalent bond, where the hydrogen atom shares its electron with the bromine atom. This results in the hydrogen atom carrying a partial positive charge and the bromine atom carrying a partial negative charge, making it a polar molecule. This bond is relatively strong and stable compared to other hydrogen halide bonds.
Is there a hydrogen bonding in HBr?
No, hydrogen bonding does not occur in HBr because it does not have a hydrogen atom bonded to a highly electronegative element like oxygen, nitrogen, or fluorine. Hydrogen bonding requires a hydrogen atom directly bonded to one of these highly electronegative elements.
What intermolecular forces are displayed by HBr?
HBr exhibits van der Waals forces, specifically dipole-dipole interactions, due to the difference in electronegativity between hydrogen and bromine. This leads to a partial positive charge on hydrogen and a partial negative charge on bromine, resulting in an attraction between the molecules.
What is the name of the compound Ga?
HBr is the chemical formula for Hydrogen Bromide. It has one hydrogen atom and one bromine atom. At normal room temperature and pressure it is a gas. When mixed in water HBr is called hydrobromic acid.
What is the charge associated with each side of the HBr molecule?
In the HBr molecule, the hydrogen atom has a partial positive charge (+δ) due to its low electronegativity compared to bromine. The bromine atom has a partial negative charge (-δ) because it is more electronegative and attracts the shared electrons more strongly, resulting in an uneven distribution of electron density in the molecule.
What is the percentage of hydrogen in hydrogen Bromide?
It all depends on what you're looking for. If you mean ratio of atoms, It is a one:one ratio, so 50% each If you mean mass, 1.0125% of the mass of one molecule is hydrogen and the other 98.9875% is bromine.
What type of intermolecular forces would you expect to find in a liquid sample of HBr?
In a liquid sample of HBr, you would expect to find predominantly dipole-dipole interactions and some hydrogen bonding. Hydrogen bonding occurs between the hydrogen atom of one molecule and the lone pair of electrons on the bromine atom of another molecule in HBr.
How many valence electrons does HBr have?
Hydrogen has 1 valence electron. Bromine has 7 valence electrons. When hydrogen and bromine react, the bromine atom 'steals' the hydrogen atom's only electron. The hydrogen atom then has no electrons and the bromine atom has 8 valence electrons. The two atoms are now ions because their number of protons does not equal their number of electrons. The bromine atom is now a bromide anion and the hydrogen atom is now a hydrogen cation (a proton). The two ions remain together, ionicly bonded and together are called hydrogen bromide.
