Two statements are given below. Statement I: Nitrogen has more ionization enthalpy and electronegativity than beryllium Statement II: $\mathrm{CrO}_3, \mathrm{~B}_2 \mathrm{O}_3$ are acidic oxides Correct answer is
  1. Both statements I and II are correct
  2. Both statements I and II are not correct
  3. Statement I is correct, but statement II is not correct
  4. Statement I is not correct, but statement II is correct

Solution

Ionization enthalpy depends on the (i) Size of the atom (ii) Effective nuclear charge (iii) Electronic configuration.
In periodic table left to right ionisation enthalpy increases and nitrogen have half-field electronic configuration so its ionisation enthalpy is more. $\mathrm{B}_2 \mathrm{O}_3$ (Borontrioxide) and $\mathrm{CrO}_3$ is acidic oxide. So both statements are correct.
