Question

The correct statement with respect to the property of IV B group elements is:

• A. their metallic nature decreases from carbon to lead
• B. the stability of +2 oxidation state increases from carbon to lead
• C. IP value increases from carbon to lead
• D. atomic radius decreases from carbon to lead

Answer 1

Answer: (B)

the stability of +2 oxidation state increases from carbon to lead

Metallic nature increases from top to bottom due to decrease in electronegativity. Also, ionisation potential values decrease from top to bottom due to increase in atomic radius of element. However, stability of +2 oxidation state increases and +4 oxidation state decreases from top to bottom due to inert pair effect.
