Which one of the following statements is not correct?

Which one of the following statements is not correct?

Options

  1. AMoissan boron is amorphous
  2. BThe reaction between boron and concentrated HNO3\mathrm{HNO}_3 gives N2O\mathrm{N}_2 \mathrm{O}
  3. CAmorphous boron on heating with oxygen forms B2O3\mathrm{B}_2 \mathrm{O}_3
  4. DBoron is a non-conductor of electricity

Correct answer

B. The reaction between boron and concentrated HNO3\mathrm{HNO}_3 gives N2O\mathrm{N}_2 \mathrm{O}

Step-by-step solution

Boron reacts with concentrated HNO3\mathrm{HNO}_3 to give orthoboric acid and nitrogen dioxide. B+3HNO3⟶H3BO3+3NO2\mathrm{B}+3 \mathrm{HNO}_3 \longrightarrow \mathrm{H}_3 \mathrm{BO}_3+3 \mathrm{NO}_2
