In the ( \text{SnCl}_5^- ) ion, tin (Sn) is the central atom and is bonded to five chloride ions (Cl) through covalent bonds. The tin atom has a formal oxidation state of +4, and the overall negative charge of the ion results from an additional electron that contributes to the bonding structure. In this configuration, there are no lone pairs on the tin atom, as all its valence electrons are involved in bonding with the surrounding chlorine atoms. The geometry of ( \text{SnCl}_5^- ) is trigonal bipyramidal, reflecting the arrangement of the five bonding pairs.

How many lone pair and bonding pair in phosphine?
In phosphine (PH3), there are three lone pairs and three bonding pairs.
How does a lone pair disort the molecular shape?
The lone pair forces bonding atoms away from itself
What effect does a lone electron have on a molecular shape?
The lone pair pushes bonding electron pairs away.
Why the lone pair lone pair repulsion is maximum?
Lone pair-lone pair repulsion is maximum because both lone pairs are localized around the same atom, leading to a strong electrostatic repulsion due to their negative charge densities being in close proximity. This results in a greater repulsion compared to other interactions like lone pair-bonding pair or bonding pair-bonding pair repulsions.
Why do lone pairs reduce bond angles?
Lone pairs reduce bond angles because they occupy more space than bonding pairs of electrons. This increased repulsion from the lone pairs pushes the bonding pairs closer together, resulting in smaller bond angles. Additionally, lone pairs are not involved in bonding interactions, so they exert a stronger repulsive force on adjacent bonding pairs, further distorting the geometry of the molecule.
What is the molecular geometry SnCl5-?
The molecular geometry of SnCl5- is square pyramidal. This is because the central tin atom has five bonding pairs and no lone pairs, leading to a trigonal bipyramidal electron geometry. The lone pair occupies one of the equatorial positions, resulting in a square pyramidal molecular geometry.
How many lone pair and bonding pair in phosphine?
In phosphine (PH3), there are three lone pairs and three bonding pairs.
Why does the repulsion between lone pairs are stronger than the repulsion between bonding pairs or between one bonding pair and a lone pair?
Repulsion between lone pairs is stronger because they are closer to the nucleus and repel more strongly than bonding pairs. Lone pairs have less electron-cloud shielding compared to bonding pairs, resulting in increased repulsion. This leads to lone pairs pushing each other apart more forcefully than bonding pairs do.
What effect does a lone electron pair have on molecular shape?
The lone pair pushes bonding electron pairs away.
What are lone pairs in bonding?
because they are not paired....
What is a lone pair from apexvs?
In chemistry, a lone pair is a pair of valence electrons that are not involved in bonding and are therefore considered non-bonding. Lone pairs are found in molecules with a structure that includes regions of non-bonding electrons. They can affect the shape and chemical properties of molecules.
