FAQs on Chemical Reactivity of Transition Elements Video Lecture - Chemistry for JEE Main & Advanced

1. What are transition elements in chemistry?
Ans. Transition elements, also known as transition metals, are a group of elements in the periodic table that have partially filled d or f orbitals in their atomic structure. These elements are located in the d-block of the periodic table and have unique chemical properties due to their electron configuration.
2. How do transition elements exhibit chemical reactivity?
Ans. Transition elements exhibit chemical reactivity due to the presence of partially filled d orbitals in their electron configuration. This allows them to form multiple oxidation states and participate in various types of chemical reactions, such as redox reactions, coordination reactions, and catalytic reactions.
3. What is the significance of the electron configuration in determining the chemical reactivity of transition elements?
Ans. The electron configuration of transition elements determines their chemical reactivity. The partially filled d orbitals can easily accept or donate electrons, allowing the transition elements to form various compounds and exhibit different oxidation states. This versatility in electron configuration makes them important in many biological, industrial, and environmental processes.
4. How do transition elements act as catalysts?
Ans. Transition elements act as catalysts due to their ability to change their oxidation states easily and form stable complexes with reactant molecules. The presence of transition metals in catalysts can provide an alternative reaction pathway with lower activation energy, facilitating the reaction while remaining unchanged themselves. This property is widely utilized in industrial processes and biochemical reactions.
5. What are some examples of chemical reactions involving transition elements?
Ans. Some examples of chemical reactions involving transition elements include redox reactions, such as the oxidation of iron to form rust (Fe2O3), coordination reactions, such as the formation of complex ions with ligands, and catalytic reactions, such as the Haber-Bosch process where iron catalysts are used to produce ammonia from nitrogen and hydrogen. These reactions highlight the diverse chemical reactivity of transition elements.
