The number of compounds among the following which on heating give at least two paramagnetic species is:

NaNO₃ at 800 °C, Na₂CO₃, NaHCO₃, CaCO₃, LiNO₃, Mg(NO₃)₂,Ca(NO₃)₂,

Answer:
3
Solution:

On heating, only LiNO₃, Mg(NO₃)₂ and Ca(NO₃)₂ decompose to give NO₂ and O₂, both of which are paramagnetic species.
NaNO₃ gives only O₂ (one paramagnetic species), while carbonates and NaHCO₃ give only diamagnetic products.
Hence, compounds giving at least two paramagnetic species = 3.
