Question

For d-block elements, which of the following statement is incorrect: (A) d4 species, Cr2 + is strongly reducing while manganese (III) is strongly oxidizing. (B) Higher oxidation state of transition metals are stable in their oxides and fluorides. (C) Due to lanthanide contraction size of Y and La is almost same. (D) d -block elements shows variable oxidation state.

Due to lanthanide contraction size of Y and La is almost same.

Q. For d-block elements, which of the following statement is incorrect:

$d^{4}$ species, $C r^{2 +}$ is strongly reducing while manganese (III) is strongly oxidizing.

Higher oxidation state of transition metals are stable in their oxides and fluorides.

Due to lanthanide contraction size of $Y$ and $L a$ is almost same.

$d$ -block elements shows variable oxidation state.

Due to lanthanide contraction size of $Y$ and $L a$ is almost same.
