Question
The following compounds have been arranged in order of their increasing thermal stabilities. Identify the correct order :
K2CO3 (I), MgCO3 (II), CaCO3 (III), BeCO3 (VI)
K2CO3 (I), MgCO3 (II), CaCO3 (III), BeCO3 (VI)
Options
A.I < II < III < IV
B.IV < II < III < I
C.IV < II < III < I
D.II < IV < III < I
Solution
BeCO3 < MgCO3 < CaCO3 < K2CO3
IV II III I
On the basis of Fajan′s rules, they have been arranged in increasing order of yheir ionic character and so stability. is most stable due to maximum covalent character so it is least stable thermally.
IV II III I
On the basis of Fajan′s rules, they have been arranged in increasing order of yheir ionic character and so stability. is most stable due to maximum covalent character so it is least stable thermally.
