Manganate ion \(MnO_4^{2-}\)has tetrahedral structure has only \(dπ – pπ\) \(π-bonds\).
\(Fe^{3+}\) is not used as a catalyst in the conversion of \(I^–\) to \(I_2\) by \(K_2Cr_2O_7\).
\(K_2Cr_2O_7\) oxidise \(I^–\) in acidic medium easily.
The correct answer is (B): Both Statement I and Statement II are false
Let one focus of the hyperbola $ \frac{x^2}{a^2} - \frac{y^2}{b^2} = 1 $ be at $ (\sqrt{10}, 0) $, and the corresponding directrix be $ x = \frac{\sqrt{10}}{2} $. If $ e $ and $ l $ are the eccentricity and the latus rectum respectively, then $ 9(e^2 + l) $ is equal to:
The largest $ n \in \mathbb{N} $ such that $ 3^n $ divides 50! is:
All reactants need to overcome certain energy, better known as activation energy in order to form products. This activation energy is the difference between the energy of the transition state and the reactant species.
Catalysis of chemical reactions is generally divided into two categories:
