Which one of the following statements is incorrect?
ALithium nitrate and magnesium nitrate both decompose to the oxide, nitrogen dioxide and oxygen
BLithium and magnesium both form stable solid hydrogencarbonates
CBeryllium chloride and aluminium chloride are both Lewis acids soluble in organic solvents

Neither Li nor Mg forms a solid hydrogencarbonate; their bicarbonates exist only in solution, which is a diagonal similarity. The other three statements are genuine Be-Al and Li-Mg similarities.
