The Inorganic Chemistry section covers the structure, properties, reactions, and applications of elements and their compounds, forming a core pillar of Class 11–12 Chemistry and undergraduate syllabi. This category is designed for school students, undergraduate learners, and competitive exam aspirants, with strong emphasis on NCERT alignment, conceptual clarity, and exam relevance.
In this section, you will study:
Periodic table and periodic trends – atomic size, ionization energy, electronegativity, and reactivity
Chemical bonding and molecular structure – ionic, covalent, metallic bonding, VBT, MOT, and hybridization
Hydrogen and s-block elements – properties, compounds, and applications
p-block elements – group-wise chemistry, important compounds, and trends
d- and f-block elements – transition metals, coordination behavior, and properties
Coordination compounds – nomenclature, isomerism, bonding theories, and applications
Qualitative inorganic analysis – identification of ions and systematic analysis
Industrial and biological importance of inorganic compounds
NCERT- and UG-aligned explanations, supported by reaction mechanisms, tables, diagrams, MCQs, numericals, and PYQs
The content is structured to build strong fundamentals, improve memorization through logic, and help students tackle both theoretical and application-based questions confidently.
Develop a solid foundation in Inorganic Chemistry to excel in school examinations, undergraduate courses, and competitive exams such as NEET, JEE, and CUET.
Q. What is the coordination number of the central metal ion in a complex with the formula [Co(NH3)6]Cl3?
A.
2
B.
4
C.
6
D.
8
Solution
The coordination number is determined by the number of ligands attached to the central metal ion. In this case, there are six NH3 ligands, giving a coordination number of 6.
Q. What is the coordination number of the complex [Co(NH3)6]Cl3?
A.
4
B.
6
C.
2
D.
8
Solution
The coordination number is determined by the number of ligand donor atoms bonded to the central metal ion. In [Co(NH3)6]Cl3, there are six ammonia ligands, giving a coordination number of 6.
Q. What is the effect of increasing the oxidation state of a transition metal on its ability to act as a Lewis acid?
A.
Increases
B.
Decreases
C.
No effect
D.
Varies unpredictably
Solution
Increasing the oxidation state of a transition metal generally increases its ability to act as a Lewis acid due to a higher positive charge attracting electron pairs more strongly.
Q. What is the equivalent weight of sulfuric acid (H2SO4) for the purpose of neutralization?
A.
49 g
B.
98 g
C.
24.5 g
D.
196 g
Solution
Equivalent weight = molar mass / n, where n = number of H+ ions. Molar mass of H2SO4 = 98 g/mol, n = 2. Therefore, equivalent weight = 98 g / 2 = 49 g.
