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.

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
