The correct order regarding the electronegativity of hybrid orbitals of carbon is:

Which of the following is the most basic oxide?

Which of the following is not a correct statement?

Which of the following species has a linear shape?

In which of the following molecules are all the bonds not equal?

Which one of the following orders is not in accordance with the property stated against it?

Copper sulphate dissolves in excess of $\mathrm{KCN}$ to give:

In which of the following pairs are both the ions coloured in aqueous solution- [At. No. : \(\mathrm{Sc}=21, \mathrm{Ti}=22, \mathrm{Ni}=28, \mathrm{Cu}=29, \mathrm{Co}=27\)]

$\mathrm{Al}_2 \mathrm{O}_3$ can be converted to anhydrous $\mathrm{AlCl}_3$ by heating:

Which of the following is not isostructural with $\mathrm{SiCl}_4$ ?

The electronegativity difference between $\mathrm{N}$ and $\mathrm{F}$ is greater that that between $\mathrm{N}$ and $\mathrm{H}$ yet the dipole moment of $\mathrm{NH}_3$ (1.5 D) is larger than that of $\mathrm{NF}_3(0.2 \mathrm{D})$. This is because:

$\left.\left[\mathrm{CoNH}_3\right)_4\left(\mathrm{NO}_2\right)_2\right] \mathrm{Cl}$ exhibits

More number of oxidation states are exhibited by the actinoids than by the lanthanoids. The main reason for this is:

The number of unpaired electrons in a paramagnetic diatomic molecule of an element with atomic number 16 is:

$\left[\mathrm{Cr}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right] \mathrm{Cl}_3$ (at. no. or $\mathrm{Cr}=24$ ) has a magnetic moment of 3.83 B.M. The correct distribution of $3 d$ electrons in the Chromium of the complex is:
