Gwhat is the hybridization of the central atom in the tribromide br−3 anion?

Answer : The hybridization of the central atom in the tribromide anion is,

Explanation :

The given molecule is,

Hybridization is given by the formula:

where,

V = number of valence electrons in central atom

X = number of monovalent atoms around the central atom

C = positive charge on cation

A = negative charge on anion

Bromine is the central atom which has 7 valence electrons.

Number of monovalent atoms = 2

Negative charge = 1

Now put all this values in the given formula, we get

If the value of 'H' is '5' then the hybridization is

Number of bond pair = 2

Number of lone pair = 5 - 2 = 3

Therefore, the hybridization of the central atom in the tribromide anion is,

The geometry is shown below.
