FAQs on NCERT Textbook: d & f-Block Elements - Chemistry Class 12 - NEET

1. What are the d-block elements?
Ans. The d-block elements are a group of transition metals that belong to the middle region of the periodic table. They are characterized by the filling of the 3d and 4d orbitals and include elements like iron, copper, and zinc.
2. What are the properties of d-block elements?
Ans. The d-block elements have several notable properties. They are typically good conductors of heat and electricity, have high melting and boiling points, and exhibit various oxidation states. They also tend to form colored compounds and can act as catalysts in chemical reactions.
3. How are d-block elements classified?
Ans. D-block elements are generally classified into transition metals and inner transition metals. Transition metals are further categorized into four series based on their partially filled d-orbitals (3d, 4d, 5d, and 6d), while inner transition metals are divided into lanthanides and actinides.
4. What is the importance of d-block elements in daily life?
Ans. D-block elements play a crucial role in various aspects of daily life. Transition metals like iron are essential for oxygen transport in the blood (as part of hemoglobin), while copper is used in electrical wiring and plumbing. Other d-block elements are utilized in the production of alloys, catalysts, and electronic devices.
5. How do d-block elements form coordination compounds?
Ans. D-block elements can form coordination compounds by utilizing their partially filled d-orbitals to bond with ligands. The ligands donate electron pairs to the central metal ion, resulting in the formation of complex structures. These compounds often exhibit unique properties and are widely used in fields such as medicine and industry.
