Question

Select the incorrect order for given property. (A) LiH > NaH > KH > RbH (Thermal stability) (B) CdCO 3 > CaCO 3 > K 2 CO 3 (Covalent character) (C) BeCO 3> MgCO 3> CaCO 3 (Ease of oxide formation on heating at same temperature) (D) BeF 2> MgF 2> CaF 2> SrF 2 (Solubility in water)

Tardigrade Admin · Accepted Answer

Solubility of fluorides of IIA BeF 2 > BaF 2 > SrF 2 > CaF 2 > MgF 2 ( BeF 2. is most solúble )

Q. Select the incorrect order for given property.

$L i H > N a H > KH > R b H$ (Thermal stability)

$C d C O_{3} > C a C O_{3} > K_{2} C O_{3}$ (Covalent character)

$B e C O_{3} > M g C O_{3} > C a C O_{3}$ (Ease of oxide formation on heating at same temperature)

$B e F_{2} > M g F_{2} > C a F_{2} > S r F_{2}$ (Solubility in water)

Solubility of fluorides of $II A$

$B e F_{2} > B a F_{2} > S r F_{2} > C a F_{2} > M g F_{2}$

$(B e F_{2}$ is most solúble $)$
