Question

The products obtained on heating LiNO₂ will be :
(a) Li₂O+ NO₂ +O₂ (b) Li₃N + O₂
(c) Li₂O + NO+ O₂ (d) LiNO₃ + O₂

Answer 1

The products obtained on heating LiNO₂ will be : Li₂O + NO+ O₂

• Option (c) is correct.
• Lithium nitrate when heated, decompose to produce  nitrogen dioxide - a poisonous gas.
• $LiNO_3$  → $Li_2O + NO_2+O_2$
• ⇒
• $4LiNO_3$ → $2Li_2O + 4NO_2 + O_2$

Answer 2

The products will be Li₂O+ NO₂ +O₂.

Explanation:

• Lithium is an alkali metal belonging to group 1 of periodic table.

• Lithium being very small in size and lacking any d orbital, has several exceptions in its character than other alkali metals.

• Like, when sodium or potassium nitrate is heated, it gives sodium nitrite and oxygen gas.

• But lithium nitrite is very unstable to exist.

• So it breaks into lithium oxide and nitrogen dioxide and oxygen.

• So,

• 4 LiNO3 = 2Li2O + 4NO2 +O2.
