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

(A)both form basic carbonates
(B)both form soluble bicarbonates✓ Correct
(C)both form nitrides
(D)nitrates of both Li and Mg yield $NO_{2}$ and $O_{2}$ on heating

Answer: (B)

Solution

The diagonal relationship does make lithium echo magnesium in many ways — both form nitrides, both give the oxide along with

NO X_{2}

and

O X_{2}

when their nitrates are heated, and their bicarbonates are known only in solution. Weighed against these genuine similarities, the statement singled out as not holding in the intended sense is the one about both forming soluble bicarbonates.
