Q7 / 180 · KCET 2019 · Chemistry

Incorrect statement with reference to \( \mathrm{Ce}(\mathrm{Z}=58) \)

A
Atomic size of \( C e \) is more than that of Lu.
B
Ce shows common oxidation states of \( +3 \) and \( +4 \).
Correct answer
C
\( \mathrm{Ce}^{4+} \) is a reducing agent.
D
Ce in \( +3 \) oxidation state is more stable than in \( +4 \).

Solution

(C)
\( C e^{4+} \) is an oxidizing agent.

Hence, the correct answer is option: 'C'.
