Question

The correct statement among the following is :

A

Sn2+ is an oxidizing agent while Pb4+ is a reducing agent.

B

Sn2+ and Pb2+ both are oxidizing agents.

C

Sn4+ is a reducing agent while Pb4+ is an oxidizing agent.

D

Sn2+ is a reducing agent while Pb4+ is an oxidizing agent.

Step-by-Step Solution

In Group 14 elements, the stability of the higher oxidation state (+4) decreases and the stability of the lower oxidation state (+2) increases down the group due to the inert pair effect. For tin (Sn), the +4 state is more stable than +2, so Sn2+ readily loses two electrons to form Sn4+, acting as a reducing agent. For lead (Pb), the +2 state is highly stable compared to +4 due to a strong inert pair effect, meaning Pb4+ easily gains two electrons to form Pb2+, thus acting as a strong oxidizing agent.

Exam Context & Concepts Covered

This question aligns with the NEET CHEMISTRY syllabus, specifically targeting concepts from P Block Elements. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
