What is the oxidation number of CBr4?

The oxidation number of carbon in CBr4 is +4 because bromine is more electronegative than carbon and is assigned an oxidation number of -1 each. Since there are four bromine atoms in CBr4, the total oxidation number of bromine is -4. The sum of the oxidation numbers in a compound must equal zero, so the carbon must have an oxidation number of +4 to balance the negative oxidation numbers from the bromine atoms.


What is the oxidation number of C in the compound CH2Br2?

In CH2Br2, carbon has an oxidation number of -2 because hydrogen has an oxidation number of +1 and bromine has an oxidation number of -1. The sum of the oxidation numbers in a neutral compound is zero.


How can bromine oxidation harm the ozone layer?

Bromine oxidation causes ozone depletion. Bromine utilizes the oxygen from ozone to deplete it.


In which compound does bromine have an oxidation number of plus 7?

Actually there are a few KBrO3 or NaBrO3 etc - in the bromate ion, bromine is in oxidation state +7


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 oxidation number of bromine in HOBr?

The oxidation number of bromine in HOBr is +1. This is because the oxidation number of oxygen is typically -2 and the overall compound is neutral, so the oxidation number of hydrogen is +1. This leaves bromine with an oxidation number of +1 to balance the compound.


What is the oxidation number of Al in Al2Br6?

The oxidation number of Al in Al2Br6 is +3. Each bromine atom has an oxidation number of -1, and since the compound is neutral, the sum of the oxidation numbers must equal zero. Hence, each Al atom must have an oxidation number of +3 to balance the -6 from the bromine atoms.


What is the oxidation number of bromine in KBr?

The oxidation number of bromine in KBr is -1. In ionic compounds, the oxidation number of the cation (K+) is always equal to its charge, which is +1. Therefore, the oxidation number of bromine must be -1 to balance the overall charge of the compound.


What is the oxidation of Br2-?

Each Br atom has an oxidation number of zero.


What are oxidation numbers of AlBr3?

In AlBr3, aluminum (Al) has an oxidation number of +3, while each bromine (Br) atom has an oxidation number of -1. This is because aluminum typically forms 3+ cations, while bromine typically forms 1- anions.


What is the oxidation state of an individual bromine atom in?

Bromine typically exists in the -1 oxidation state in ionic compounds. In elemental form or as part of a molecule, bromine can have various oxidation states ranging from -1 to +7.


What is the oxidation number of Br-?

The oxidation number of Br- is -1. Bromine typically has an oxidation state of -1 when it forms an ion by gaining one electron.
