In the above compounds correct order of reactivity in electrophilic substitution reactions will be

Given below are two statements :
Statement (I): Experimentally determined oxygen-oxygen bond lengths in the \(\mathrm{O}_3\) are found to be same and the bond length is greater than that of a \(\mathrm{O}=\mathrm{O}\) (double bond) but less than that of a single \((O-O)\) bond.
Statement (II) : The strong lone pair-lone pair repulsion between oxygen atoms is solely responsible for the fact that the bond length in ozone is smaller than that of a double bond \((\mathrm{O}=\mathrm{O})\) but more than that of a single bond \((\mathrm{O}-\mathrm{O})\).
In the light of the above statements, choose the correct answer from the options given below :

The correct order of bond dissociation energy among \(N_2, O_2, O_2^-\) is shown in which of the following arrangements?

Choose the correct answer from the options given below:

An aqueous solution of volume \(300\,cm ^3\) contains \(0.63\,g\) of protein. The osmotic pressure of the solution at \(300\,K\) is \(1.29\,mbar\). The molar mass of the protein is \(.........\,g\,mol ^{-1}\) Given : \(R =0.083\,L\,bar\,K ^{-1} mol ^{-1}\)

At \( 27^{\circ}C \) in presence of a catalyst, activation energy of a reaction is lowered by 10 kJ \( mol^{-1} \). The logarithm ratio of \( \frac{k(catalysed)}{k(uncatalysed)} \) is ....
(Consider that the frequency factor for both the reactions is same)

Hemoglobin contains \(0.34 \%\) of iron by mass. The number of \(Fe\) atoms in \(3.3 g\) of hemoglobin is.(Given : Atomic mass of \(Fe\) is \(56\,u , N _{ A }\) in \(6.022\) \(\left.\times 10^{23} mol ^{-1}\right)\)

Let \(\dfrac{x^2}{f(a^2+7a+3)} + \dfrac{y^2}{f(3a+15)} = 1\) represent an ellipse with major axis along \(y\)-axis, where \(f\) is a strictly decreasing positive function on \(\mathbb{R}\). If the set of all possible values of \(a\) is \(\mathbb{R} - [\alpha, \beta]\), then \(\alpha^2+\beta^2\) is equal to:

The urns \(A, B\) and \(C\) contain \(4\) red, \(6\) black;\(5\) red,\(5\) black and \(\lambda\) red,\(4\) black balls respectively. One of the urns is selected at random and a ball is drawn. If the ball drawn is red and the probability that it is drawn from urn \(C\) is \(0.4\) then the square of the length of the side of the largest equilateral triangle, inscribed in the parabola \(y^2=\lambda x\) with one vertex at the vertex of the parabola is

A uniform thin rod \(AB\) of length \(L\) has linear mass density \(\mu \left( x \right) = a + \frac{{bx}}{L}\) , where \(x\) is measured from \(A\). If the \(CM\) of the rod lies at a distance of \(\left( {\frac{7}{12}} \right)L\) from \(A\), then \(a\) and \(b\) are related as

The reaction of white phosphorus on boiling with alkali in inert atmosphere resulted in the formation of product \('A'\). The reaction \(1\, mol\) of \('A'\) with excess of \(AgNO _{3}\) in aqueous medium gives ............... mol\((s)\) of \(Ag\). (Round off to the Nearest Integer).

A current of \(10.0\, A\) flows for \(2 .00\, h\) through an electrolytic cell containing a molten salt of metal \(X\). This results in the decomposition of \(0 .250\, mol\) of metal \(X\) at the cathode. The oxidation state of \(X\) in the molten salt is \((F = 96,500\, C\))

Mean of \(5\) observations is \(7.\) If four of these observations are \(6, 7, 8, 10\) and one is missing then the variance of all the five observations is
