Vedclass · Answer

(A) According to Fajan's rule,the polarising power of a cation is inversely proportional to its size. As the size of the cation increases down the group $(Be^{2+} Since lower polarising power leads to higher ionic character,the ionic character increases as the size of the cation increases. Therefore,the correct order of increasing ionic character is $BeBr_2 < MgBr_2 < CaBr_2 < BaBr_2$.

The correct order of the increasing ionic character is
