Why is PbCl4 more stable than PbCl2?

This is due to inert pair effect. Pb has four electrons in its outermost shell, two are in s orbital and two in the p orbital. … The s electrons are inert and are not that easily removed to give the group valency of 4.

Which among the halide is most stable PbCl4 PbCl2 pbi4 pbf2?

PbCl2 is more stable than PbCl4.

Which is more stable PbCl2 or SnCl2?

Since Pb is more down the group than Sn, it’s stable with +2 oxidation state where Sn can exhibit both +2&+4 but +4 is more stable due to which SnCl2 is a strong reducing agent.

Which is more stable Gecl2 or PbCl2?

Gecl4 is more stable than Gecl2 but pbcl2 is more stable than pbcl4.

Which is more stable pbf2 or PbCl2?

In Pbcl2, the temperature is low as compared to pbf2 in which density, as well as temperature, is high. Even in term of thermal expansion, pbcl2 is high than pbf2.

Which among the halide is most stable PbCl4?

PbCl2
PbCl2 is more stable than PbCl4 . >>PbCl2 is more stable than PbCl4 .

Why is PbCl4 less stable than sncl4?

As we move down the group from C to Pb, the stability of +4 oxidation state decreases while that of +2 oxidation state increases due to the same inert pair effect. … Therefore, for Pb +2 oxidation state becomes more stable than +4 oxidation state and vice-versa for Sn.

Which is more stable GeCl2 or GeCl4?

Correct option c GeCl2 is more stable than GeCl2Explanation:GeCl4 is more stable than GeCl2. Ge has greater tendency to form +4 state than +2 state.

Why GeCl4 is more stable than GeCl2?

Now according to the question GeX4 is more stable because it does not have a full valence so it is unfilled valance so GeX4 is more stable than GeX2. we know , oxidation state of +2 is more stable than +4 . due to inert pair effect.

Which is more stable PbCl2 or SnCl4?

PbCl4 is less stable then SnCl4 , PbCl2 is more stable then SnCl2 .

Which is an oxidizing agent PbCl4 or PbCl2?

PbCl4 is powerful oxidizing agent.

Which is more stable SnCl4 or SnCl2?

Sncl2 is more stable than sncl4. According, to the rule more charge has higher tendency to polarise the surrounding atom which tends to introduce a covalent character in molecule. sncl4 tends to have higher positive charge and its size is smaller. Hence, sncl4 is covelant and sncl2 is iocnic and stable.

What is inert pair effect out of PbCl4 and SnCl4 which one shows higher oxidising nature?

Inert pair effect: Reluctance of outermost s-orbital electrons to take part in the reaction. Thus, lead show stable +2 oxidation state while tin shows stable +4 oxidation state. So PbCl4 tends to get reduced easily and therefore oxidise others. Hence, PbCl4 is stronger oxidising agent than SnCl4​.

Which of these is the most stable ccl2 sicl2 SnCl2 PbCl2?

Due to inert pair effect +2 oxidation state of Pb is more stable than +4 . But in case of Sn it’s +4 oxidation state is more stable than +2 oxidation state. Thus, PbCl4 is less stable than SnCl4, while PbCl2 is more stable than SnCl2.

Why PbX2 is more stable than PbX4?

Due to inert pair effect +2 oxidation state of Pb is more stable than its +4 oxidation state. Consequently PbX2 in which the oxidation state of Pb is +2 is more stable than PbX4 in which the oxidation state of Pb is +4.

Which of the following is ionic PbCl2 SnCl4 PbCl4 sicl4?

Lead (II) chloride (PbCl2) is ionic than Pbcl4. Pbcl4 is a covalent compound. Visit BYJU’S – The Learning App to know about various chemicals in detail.

Which of the following compounds PbCl2 PbCl4 SnCl2 SnCl4 is most covalent Why?

In SnCl2, Sn has +2 oxidation state. Whereas in SnCl4, Sn has +4 oxidation state. According to Fajan’s rule, the central metal with more oxidation number will be considered to be more covalent. Therefore, SnCl4 is more covalent than SnCl2.

Is sicl2 stable?

This is the oxidation state shown by carbon and silicon in CCl4 and SiCl4. These therefore have no tendency to split up to give dichlorides. However, the relative stability of the +4 oxidation state falls as you go down the Group, and the +2 oxidation state becomes the most stable by the time you get to lead.

Why is SnCl2 more easily formed than SnCl4?

Tin contains two electrons in d-orbital and hence show two oxidation state of +2 and +4 due to inert pair effect. as we move down the group (I.e. from Ge to Pb) stability of +2 oxidation state increases while that of +4 oxidation state decreases. Therefore, SnCl2 is more formed than SnCl4.

Which is more ionic PbCl4 or SnCl4?

Yes,SnCl4 has more covalent character than SnCl2 . … You can also say this as SnCl2 is more ionic than SnCl4, as SnCl2 can easily dissociate into its ions when in aqueous form ( strong electrolyte ) while SnCl4 partially dissociates making it a weak electrolyte.

Why PbCl2 is ionic whereas PbCl4 is covalent?

The charge on Pb in PbCl2 is +2 and PbCl4 is +4. According to Fajan’s rule, greater the charge on the cation, more is its ability to polarize the bonding electrons towards itself giving the compound a higher covalent character. PbCl has a greater charge and hence is covalent.
