MCQ (Single Correct Answer)

-1

$$C{e^{ + 3}},\,\,L{a^{ + 3}},\,\,P{m^{ + 3}}\,\,$$ and $$Y{b^{ + 3}}\,\,$$ have ionic radial in the increasing order as

$$L{a^{ + 3}}\,\, < C{e^{ + 3}}\,\, < P{m^{ + 3}}\,\, < Y{b^{ + 3}}$$

$$Y{b^{ + 3}}\,\, < P{m^{ + 3}}\,\, < C{e^{ + 3}}\,<\,L{a^{ + 3}}$$

$$L{a^{ + 3}}\,\, = C{e^{ + 3}}\,\, < P{m^{ + 3}}\,\, < Y{b^{ + 3}}$$

$$Y{b^{ + 3}}\,\, < P{m^{ + 3}}\,\, < L{a^{ + 3}}\,\, < C{e^{ + 3}}$$
