Chemical Reactivity Group IV Elements Reaction with Halogens and the Inert Pair Effect

The video tutorial discusses the carbon family elements forming tetrahalides of type MX4, which are covalent and exhibit SP3 hybridization, resulting in a tetrahedral shape. It highlights that only SNF4 and PBFO are ionic among these halides. The thermal stability and volatility of tetrahalides decrease down the group, inversely proportional to their molecular weight. The video also explains why PBI4 does not exist due to the strong oxidizing nature of the PB4+ ion, which is less stable than the PB2+ ion due to the inner pair effect.

What type of hybridization occurs in the central element of tetrahalide MX4?

• dSP3

• SP

• SP3

• SP2

Which of the following tetrahalides is ionic in nature?

• GeCl4

• CCl4

• SiCl4

• SNF4

What happens to the thermal stability of tetrahalides as you move down the carbon family group?

• It remains constant

• It decreases

• It increases

• It fluctuates

Why does PBI4 not exist?

• Due to its covalent nature

• Because it is highly volatile

• Because PB4+ is a strong oxidizing agent

• Due to its high molecular weight

What is the reason for the greater stability of PB2+ ion compared to PB4+ ion?

• Higher molecular weight

• Inner pair effect

• Greater ionic radius

• Lower oxidation state
