Question

Incorrect statement is: (A) NaHCO 3 and KHCO 3 have same crystal structure (B) On heating LiNO 3 decomposes into Li 2 O and NO 2 (C) Among alkali metals, Li metal impart red colour to flame (D) Li 2 SO 4 does not form alum

Tardigrade Admin · Accepted Answer

The crystal structures of NaHCO 3 and KHCO 3 both show hydrogen bonding but are different. In NaHCO 3, the HCO 3-ions are linked into an infinite chain, while in KHCO 3, a dimeric anion is formed.

Q. Incorrect statement is:

$N a H C O_{3}$ and $KH C O_{3}$ have same crystal structure

On heating $L i N O_{3}$ decomposes into $L i_{2} O$ and $N O_{2}$

Among alkali metals, Li metal impart red colour to flame

$L i_{2} S O_{4}$ does not form alum

The crystal structures of $N a H C O_{3}$ and $KH C O_{3}$ both show hydrogen bonding but are different. In $N a H C O_{3}$ , the $H C O_{3}^{-}$ ions are linked into an infinite chain, while in $KH C O_{3}$ , a dimeric anion is formed.
