Vedclass · Answer

(B) The thermal stability of carbonates increases as the polarizing power of the cation decreases.$1.$ $BeCO_3$ $(IV)$ is the least stable due to the high polarizing power of $Be^{2+}$.$2.$ Among alkaline earth metal carbonates ($II$ and $III$),stability increases down the group: $BeCO_3 $3.$ Alkali metal carbonates $(I)$ are much more stable than alkaline earth metal carbonates because alkali metals have lower charge $(+1)$ and lower polarizing power.Therefore,the correct order of increasing thermal stability is $IV < II < III < I$.

The following compounds have been arranged in order of their increasing thermal stabilities. Identify the correct order.
$I.$ $K_2CO_3$ $II.$ $MgCO_3$
$III.$ $CaCO_3$ $IV.$ $BeCO_3$
