Pick out the statement (s) which is (are) not true about the diagonal relationship of Li and Mg
(i) Polarising powers of

\mathrm{L}{\mathrm{i}^ + }\mathrm{andM}{\mathrm{g}^{2 + }}

are almost same
(ii) L like Li, Mg decomposes water very fast.
(iii)

\mathrm{LiCl andMgC}{\mathrm{l}_2}

are deliquescent
(iv) Like Li, Mg does not form solid bicarbonates.

View answer and explanation

Correct option: C

Only (ii)

Option C (Only (ii)) is correct because Lithium decomposes water slowly, unlike Magnesium which does not decompose water very fast.
