The answer is- is octahedral in electronic and molecular geometry with 6 Fluorine atoms bonded to central atom S.
Lewis structures are the diagrams in which the valence electrons of the atoms of a compound are arranged around the atoms showing the bonding between the atom and the lone pair of electrons existing in the molecule.
Determine the molecular geometry of .
- Valence Shell Electron Pair Repulsion theory is commonly known as VSEPR theory and it helps to predict the geometry of molecules.
- According to this theory, electrons are arranged around the central atom of the molecule in such a way that there is minimum electrostatic repulsion between these electrons.
- Now, calculate the total number of valence electrons in
.
Valence electrons of S = 6
Valence electrons of F = 7
Thus, the valence electrons in are-
- The Lewis structure of
- In the structure, the number of atoms bonded to central atom (S) = 6.
- Number of non-bonding electron pairs on the central atom = 0 (as all the valence electrons are bonded to F).
- Electronic geometry in case of 6 bond pairs is octahedral.
- Molecular geometry us also octahedral with bond angles 90°.
- Central atom is sp3d2 hybridised.

Answer: The molarity of the borax solution is 0.107 M
Explanation:
The neutralization reaction is:
According to neutralization law:
where,
= basicity of
= 2
= acidity of borax = 2
= concentration of
= 1.03 M
= concentration of borax =?
= volume of
= 2.07ml
= volume of borax = 20.0 ml
Now put all the given values in the above law, we get the molarity of borax:
By solving the terms, we get :
Thus the molarity of the borax solution is 0.107 M
