Chemical Bonding – Interactive PYQ Quiz

Topic: Molecular Geometry & VSEPR | JEE Main PYQs

Q1. [16 March 2021 | Shift-1]

Assertion: H–O–H bond angle in water is 104.5°.
Reason: Lone pair–lone pair repulsion is maximum.

Lone pair–lone pair repulsion compresses bond angle below 109.5°.

Q2. [JEE Main 2024]

Correct increasing order of bond angles:

ClF₃ (T-shape) < PF₃ (pyramidal) < BF₃ (120°).

Q3. [11 April 2023 | Shift-1]

Match geometries correctly:

H₂O⁺ → pyramidal, acetylide → linear, NH₃ → pyramidal, ClO₂⁻ → bent.

Q4. [27 Jan 2022 | Shift-II]

Incorrect statement for PCl₅:

Axial bonds are longer and weaker.

Q5. [5 Sept 2020 | Shift-1]

Solid-state structure of PCl₅:

PCl₅ exists as ionic lattice in solid state.

Q6. [29 July 2022 | Shift-1]

Odd-electron + expanded octet pair:

NO is odd-electron; BCl₃ violates octet.

Indefinite Integration: Complete Notes for JEE Mains & Advanced

Indefinite Integration – Complete Revision (JEE Mains & Advanced) Indefinite Integration is not about memorising random formulas — it is about identifying forms . JEE strictly rotates questions around a fixed set of standard integrals and methods . This note covers the entire official syllabus with zero gaps. 1. Definition \[ \int f(x)\,dx = F(x)+C \quad \text{where } \frac{dF}{dx}=f(x) \] 2. ALL Standard Integrals (Must Memorise) \(\int x^n dx = \frac{x^{n+1}}{n+1}+C,\; n\neq-1\) \(\int \frac{1}{x}dx = \ln|x|+C\) \(\int e^x dx = e^x+C\) \(\int a^x dx = \frac{a^x}{\ln a}+C\) \(\int \sin x dx = -\cos x + C\) \(\int \cos x dx = \sin x + C\) \(\int \sec^2 x dx = \tan x + C\) \(\int \csc^2 x dx = -\cot x + C\) \(\int \sec x\tan x dx = \sec x + C\) \(\int \csc x\cot x dx = -\csc x + C\) 3. SIX IMPORTANT FORMS (JEE CORE) Form 1: \(\int \frac{1}{x^2+a^2}dx\) \[ = \frac{1}{a}\tan^{-1}\frac{x}{a}+C \] Form 2: \(\int \frac{1}{\sqrt{a^2-x^2}}dx\) \[...
