Which of the following series correctly represents relations between the elements from X to Y?
\(X\to Y\)
\(X\to Y\)
\(_{3}Li \to_{19}K\) - Ionization enthalpy increases.
\(_{9}F\to_{35}Br\) - Electron gain enthalpy with negative sign increases.
\(_{6}C \to_{32}Ge\) - Atomic radii increases.
\(_{18}Ar\to_{54}Xe\) - Noble character increases.
The Correct Option is C
Solution and Explanation
$e^{\ell}$ on moving down the gsaap shell number increases so its radii also increase from "C to Ge".
So, the correct option is (C): \(_{6}C \to_{32}Ge\) - Atomic radii increases.

Top JEE Main Questions
- In a hydrogen like atom, when an electron jumps from the $M$ - shell to the $L$ - shell, the wavelength of emitted radiation is $\lambda$. If an electron jumps from $N$-shell to the $L$-shell, the wavelength of emitted radiation will be :
- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:

Haloalkanes and Haloarenes - Classification
Classification of Haloalkanes and Haloarenes are as follows:
Haloalkanes and Haloarenes are Classified on the Basis of the Number of Halogen Atoms:
These are further classified as mono, di, or polyhalogen (tri-,tetra-, etc.) compounds depending on whether they contain one, two or more halogen atoms in their structures. For example;
- Monohaloalkane
- Dihaloalkane
- Trihaloalkane
Haloalkanes and Haloarenes are Classified on Compounds Containing sp3 C—X Bond (X= F, Cl, Br, I)
This class includes:
- Alkyl halides or haloalkanes (R—X)
- Allylic halides
- Benzylic halides
Haloalkanes and Haloarenes are Classified on Compounds Containing sp2 C—X Bond
This class includes:
- Vinylic halides
- Aryl halides
