MCQ
Which of these forms nitride with nitrogen at higher temperature?
  • A
    Aluminium
  • B
    Boron
  • Both $A$ and $B$
  • D
    Indium

Answer

Correct option: C.
Both $A$ and $B$
Aluminium and boron forms nitride with nitrogen at higher temperature due to the high bond energy of nitrogen. In case of aluminium, a thin oxide layer is formed so it also needs high temperature to react with nitrogen to form the nitride.
