List-I (Elements) | List-II (Properties in their respective groups) |
---|---|
(A) Cl,S | (I) Elements with highest electronegativity |
(B) Ge, As | (II) Elements with largest atomic size |
(C) Fr, Ra | (III) Elements which show properties of both metals and non metal |
(D) F, O | (IV) Elements with highest negative electron gain enthalpy |
Elements with highest electronegativity → F, O
Elements with largest atomic size → Fr, Ra
Elements which show properties of both metals and non-metals (metalloids) → Ge, As
Elements with highest negative electron gain enthalpy → Cl, S
For the reaction, \[ H_2(g) + I_2(g) \rightleftharpoons 2HI(g) \] Attainment of equilibrium is predicted correctly by:
For the reaction, \[ H_2(g) + I_2(g) \rightleftharpoons 2HI(g) \]
Attainment of equilibrium is predicted correctly by:
Let \( y = f(x) \) be the solution of the differential equation
\[ \frac{dy}{dx} + 3y \tan^2 x + 3y = \sec^2 x \]
such that \( f(0) = \frac{e^3}{3} + 1 \), then \( f\left( \frac{\pi}{4} \right) \) is equal to:
Find the IUPAC name of the compound.
If \( \lim_{x \to 0} \left( \frac{\tan x}{x} \right)^{\frac{1}{x^2}} = p \), then \( 96 \ln p \) is: 32
