NettetSolution It is Due to the phenomena of 'Inert pair effect' . In p-block of periodic table , the elements at bottom like Sn,Pb have +4 state less stable than +2 state. because bond energy released after bond formation is less than required to unpair these electrons,i.e those 2 electrons.That is +2 more stable than +4 for pb and Sn. NettetCorrect option is C) BeCO 3 has lowest thermal stability. It decomposes to give BeO and CO 2. Hence, it is placed in the atmosphere of CO 2 which prevents decomposition. Be dissolves in alkali to form [Be(OH) 4] 2−. Be 2++4OH −→[Be(OH) 4] 2−. BeF 2 forms complexes with NaF in which Be goes with anion. BeF 2+2NaF→Na 2[BeF 4] 2−.
