An element (X) is found allotropic forms.
One of the allotrope of X has the following properties.
(i) It glows in dark.
(ii) It is waxy solid.
Find out the number of oxy acids of element 'X' out of the following which have at least one –X–X– linkage:
H₂S₂O₅, H₂S₄O₆, H₄P₂O₇, H₄P₄O₁₂, H₄P₂O₆ (tetrabasic), H₂N₂O₂, H₄P₂O₅, H₆P₄O₁₃.
Answer:
1
Solution:
The element X is Phosphorus (P) due to its allotropic forms, glowing in the dark (white phosphorus), and being a waxy solid. We need to find oxyacids of P with at least one P-P linkage.
The oxyacids with P-P linkages are:
H₄P₂O₆ (tetrabasic) - contains a P-P bond.
Therefore, only 1 oxyacid from the given list has a P-P linkage.
