उत्तर
Elements of group-15 form compounds in +5 oxidation state. However, bismuth forms only one well-characterised compound in +5 oxidation state. The compound is \[\ce{BiF5}\].
Explanation:
Bismuth commonly shows +3 oxidation state instead of +5 oxidation state due to inert pair effect. But \[\ce{Bi}\] forms \[\ce{BiF5}\] compound due to high electronegativity and small size of fluorine atom.
