Question

Both lithium and magnesium display several similar properties due to the diagonal relationship; however, the one which is incorrect, is : (A) Both form nitrides (B) Nitrates of both Li and Mg yield NO2 and O2 on heating (C) Both form basic carbonates (D) Both form soluble bicarbonates

Mg forms basic carbonate 3 MgCO 3 ⋅ Mg ( OH )2 ⋅ 3 H 2 O but no such basic carbonate is formed by Li.

Q. Both lithium and magnesium display several similar properties due to the diagonal relationship; however, the one which is incorrect, is :

Both form nitrides

Nitrates of both $L i$ and $M g$ yield $N O_{2}$ and $O_{2}$ on heating

Both form basic carbonates

Both form soluble bicarbonates

Mg forms basic carbonate

$3 M g C O_{3} \cdot M g (O H)_{2} \cdot 3 H_{2} O$ but no such basic carbonate is formed by Li.
