Incorrect statement is: (a) NaHCO3 and KHCO3 have same crystal structure (b) On heating LiNO3 decomposes into Li2O and NO2 (c) Among alkali metals, Li metal impart red colour to flame (d) Li2SO4 does not form alum

Correct answer: (a) NaHCO3 and KHCO3 have same crystal structure Explanation: The crystal structures of NaHCO3 and KHCO3 both show hydrogen bonding but are different. In NaHCO3, the HCO3- ions are linked into an infinite chain, while in KHCO3, a dimeric anion is formed.

Correct answer: (a) NaHCO₃ and KHCO₃ have same crystal structure

Explanation:

The crystal structures of NaHCO₃ and KHCO₃ both show hydrogen bonding but are different. In NaHCO₃, the HCO₃^- ions are linked into an infinite chain, while in KHCO₃, a dimeric anion is formed.
