What happen when sncl4 is heated?
When SnCl4 is heated, it undergoes thermal decomposition to form SnCl2 and Cl2 gases. The decomposition reaction is: 2 SnCl4 (s) -> 2 SnCl2 (s) + Cl2 (g)
WHY SnCl2 is solid while SnCl4 volatile liquid?
SnCl2 is a solid at room temperature due to its ionic bonding and the presence of strong electrostatic forces between Sn2+ and Cl- ions, resulting in a stable crystalline structure. In contrast, SnCl4 is a covalent compound with a molecular structure, which allows it to exist as a volatile liquid; its weaker intermolecular forces make it easier for the molecules to escape into the gas phase. The difference in bonding and molecular interactions accounts for their distinct physical states at room temperature.
Why sncl4 more covalent than sncl2?
SnCl4 is more covalent than SnCl2 primarily due to the higher oxidation state of tin in SnCl4, which leads to a greater polarization of the chloride ions. The Sn4+ ion has a stronger positive charge, attracting the electron cloud of the Cl- ions more significantly, enhancing covalent character. In contrast, SnCl2, with Sn2+, exhibits less polarization and therefore has a greater ionic character. This difference in charge and polarization explains the greater covalent nature of SnCl4 compared to SnCl2.
Why is sncl2 more stable than sncl4 briefly?
SnCl2 is more stable than SnCl4 primarily due to the oxidation states of tin in these compounds. In SnCl2, tin is in a +2 oxidation state, which is more stable due to its ability to achieve a stable electron configuration. In contrast, SnCl4 has tin in a +4 oxidation state, which is less stable because it has a higher positive charge and is more susceptible to hydrolysis and other reactions. Additionally, SnCl4 can be less stable in the presence of moisture since it can readily form SnCl2 and HCl.
What is the molecular geometry of SnCl4?
The molecular geometry of SnCl4 is tetrahedral. This is because tin (Sn) has 4 bonding pairs of electrons and 0 lone pairs, leading to a symmetrical tetrahedral arrangement of the chlorine atoms around the tin atom.

Why SnCl2 is more stable than SnCl4?
SnCl2 is more stable than SnCl4 because of the lower oxidation state of tin (+2 in SnCl2 compared to +4 in SnCl4). The lower oxidation state of tin in SnCl2 leads to a higher stability due to less repulsion between the electrons. Additionally, the bond energy in the Sn-Cl bonds of SnCl2 is stronger than that in SnCl4, contributing to its stability.

What is the change in the oxidation number of Sn in the reaction 2FeCl2 plus SnCl4 -- SnCl2 plus 2FeCl3?
The oxidation number of Sn changes from +4 in SnCl4 to +2 in SnCl2, resulting in a decrease of 2.

What is the product of tin and chlorine?
There are two main products of tin and chlorine, SnCl2 and SnCl4.
How sncl4 more covalent than sncl2?
The halides in higher oxidation state posses high charge and are smaller in size as compared to the lower oxidation state halides.Thus, in higher oxidation halides the charge/radius ratio is higher which contribute to the increase in polarisation and consequently these are more covalent.(--AK)
What is the function of SnCl2 and HgCl2 in estimation of iron from plain carbon steel?
function of SnCl2 is that it acts as a reducing agent to reduce FeCl3 to FeCl2 and function of HgCl2 is to oxidize SnCl2 to SnCl4. total iron is determined after reducing ferric iron to ferrous state.
What is the for mula for tin chloride?
Tin (Sn) shows two oxidation states +2 and +4 so tin forms two types of chloride SnCl2 and SnCl4.
What is true about the equation shown below FeCl2 plus SnCl4 - SnCl2 plus FeCl3?
One important truth is that it is not balanced, because it has five chlorine atoms on the right side and only two chlorine atoms on the left. The equation should read: 2 FeCl2 + SnCl4 -> SnCl2 + 2 FeCl3. The equation also describes an oxidation-reduction reaction, in which iron ions are oxidized and tin ions are reduced.
What is the molecular geometry of SnCl4?
The molecular geometry of SnCl4 is tetrahedral. This is because tin (Sn) has 4 bonding pairs of electrons and 0 lone pairs, leading to a symmetrical tetrahedral arrangement of the chlorine atoms around the tin atom.
