Question

The coordination number and oxidation number of $X$ in the compound $\left[X\right(S{O}_4\left)\right(N{H}_3{)}_5]$ will be:

• A. $10\text{and}3$
• B. $1\text{and}6$
• C. $6\text{and}2$
• D. $6\text{and}4$

Answer 1

The correct option is C $6\text{and}2$

$\left[X\right(S{O}_4\left)\right(N{H}_3{)}_5]$ contains $X$ in $+2$ oxidation state and coordination number is $6$.
