Answer 2

According to the VSEPR theory, BrF5 has a square pyramidal shape.

The answer can be justified as:

• According to the VSEPR theory, there are some rules to be followed for predicting the geometrical shape of a compound. They are:

1. Firstly,we need to identify the central atom
2. then count the number of valence electrons on the central atom.
3. then, Add one electron for each bonding atom
4. Add or subtract electrons for depending upon the charge of electron
5. now, we divide the total by 2 to find the total number of electron pairs
6. the number we get as result is used to predict the shape.

VSEPR theory uses the AXmEn method to find the geometrical shape of compounds, where A is the central atom, X is the each atom bonded to the A (central atom) and E is the number of lone pair of electrons.

• here, BrF5 represents bromine pentafluoride.
• it represents the VSEPR theory formula through AXE method as AX5E1.
• here, A is central atom bromine ,X⁵ is number of atoms bonded to it i.e. 5 fluorine atoms and E is one pair of lone electrons.
• according to VSEPR theory, valency in central atom is 7, for each bonding we take one, so for five fluorine atoms we add 5 to it and divide the result by 2.

=(7+5)/2

=12/2

=6

6 represents square pyramidal shape for 1 pair of lone electrons.

so BrF5 is square pyramidal shape among the 4 compound given.
