The correct option with respect to the Pauling electronegativity values of the element is :
Show Hint
- \(\mathrm{Ga} \lt \mathrm{Ge}\)
- \(\mathrm{Si} \lt \mathrm{Al}\)
- \(\mathrm{Te} \gt \mathrm{Se}\)
- \(\mathrm{P} \gt \mathrm{S}\)
The Correct Option is A
Solution and Explanation
(1) Ga (1.81) < Ge (2.01): true.
(2) Si (1.90) < Al (1.61): false, since Si > Al.
(3) Te (2.1) > Se (2.55): false, since Te < Se (down the group).
(4) P (2.19) > S (2.58): false, since P < S (across the period).
Answer: (1) Ga < Ge

Top JEE Main Questions
- 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:
