Heterolysis of carbon-chlorine bond produces:

A complex has the molecular formula \(\mathrm{Co} .5 \mathrm{NH}_{3} . \mathrm{NO}_{2} . \mathrm{Cl}_{2}\). One mole of this complex produces three moles of ions in an aqueous solution. On reacting this solution with excess of \(\mathrm{AgNO}_{3}\) solution, we get 2 moles of white ppt. The complex is:

Which of the following are Lewis acids?

Arrange the following compounds in decreasing order of basicity:

\(\mathrm{I}\). Ethylamine

\(\mathrm{II}\). \(2\) - amino ethanol

\(\mathrm{III}\). \(3\) - amino - \(1\) - Propanol

In Mendeleev’s Periodic Table, gaps were left for the elements to be discovered later. Which of the following elements found a place in the Periodic Table later?

What is the structural formula of Haloalkane?

Which amongst the given plots is the correct plot for pressure (p) vs density (d) for an ideal gas?

For the following cell, calculate the emf:

\(\mathrm{Al}\left|\mathrm{Al}^{3+}(0.01 M) \| \mathrm{Fe}^{2+}(0.02 \mathrm{M})\right| \mathrm{Fe}\)

Given : \(E_{\mathrm{Al}^{3+} / \mathrm{Al}}^{\circ}=-1.66 \mathrm{~V}, E_{\mathrm{Fe}^{2+} / \mathrm{Fe}}^{\circ}=-0.44 \mathrm{~V}\)

An empty LPG cylinder weight \(14.8 \mathrm{~kg}\). When full, it weight \(29.0 \mathrm{~kg}\) and shows a pressure of \(3.47 \mathrm{~atm}\). In the course of use at ambient temperature, the mass of the cylinder is reduced to \(23.0 \mathrm{~kg}\). The final pressure inside of the cylinder is________atm. (Nearest integer) (Assume LPG of be an ideal gas)
