Easy MCQ +4 / -1 PYQ · JEE Mains 2023

Which of the following reaction is correct?

  1. A $4 \mathrm{LiNO}_{3} \stackrel{\Delta}{\longrightarrow} 2 \mathrm{Li}_{2} \mathrm{O}+4 \mathrm{NO}_{2}+\mathrm{O}_{2}$ Correct answer
  2. B $2 \mathrm{LiNO}_{3} \longrightarrow 2 \mathrm{Li}+2 \mathrm{NO}_{2}+\mathrm{O}_{2}$
  3. C $4 \mathrm{LiNO}_{3} \stackrel{\Delta}{\longrightarrow} 2 \mathrm{Li}_{2} \mathrm{O}+2 \mathrm{~N}_{2} \mathrm{O}_{4}+\mathrm{O}_{2}$
  4. D $2 \mathrm{LiNO}_{3} \stackrel{\Delta}{\longrightarrow} 2 \mathrm{NaNO}_{2}+\mathrm{O}_{2}$

Solution

<p>$\mathrm{4LiNO_3}$ $\buildrel {\mathrm{Heat}} \over \longrightarrow$ $\mathrm{2Li_2O+4NO_2+O_2}$</p> <p>$\mathrm{LiNO_3}$ on heating produces $\mathrm{Li_2O,NO_2}$ and $\mathrm{O_2}$</p>
