The covalent and vanderwaal's radii of \(\mathbf{H}\) atom respectively are :
1 \(0.37 \AA, 0.8 \AA\)
2 \(0.8 \AA, 0.37 \AA\)
3 \(0.8 \AA, 0.8 \AA\)
4 \(0.37 \AA, 0.37 \AA\)
Explanation:
Vander Waal's radii is larger than covalent \(r_v>r_c\)

Find the formula of halide of metal whose successive ionisation energies are \(x, 2 x\) and \(50 x\) \(\mathrm{kJ} / \mathrm{mol}\) respectively :
1 \(\mathrm{MX}_2\)
2 \(\mathrm{MX}_4\)
3 \(\mathrm{M}_2 \mathrm{X}\)
4 \(M X_3\)
Explanation:
\(M\) has \(2 \mathrm{e}^{-}\)in the valence shell \(\mathrm{M}\) halide : \(\mathrm{MX}_2\)
Ionisation energy and second electron gain enthalpy are endothermic processes. \( \mathrm{Cl}(\mathrm{g}) \rightarrow \mathrm{Cl}^{+}(\mathrm{g})+\mathrm{e}^{-} \) \( \mathrm{O}^{-}(\mathrm{g})+\mathrm{e}^{-} \rightarrow \mathrm{O}^{2-}(\mathrm{g}) \)
