Question

X, an allotrope of phosphorus reacts with KOH to form hypophosphoric acid (Y) along with other products. Choose a statement, among the following which is not correct about X or Y.

1.X does not show chemiluminescence

2.One P-P bond is present in acid Y

3.Allotrope X is non-poisonous and insoluble in water

4.Y cannot act as reducing agent​

Answer 1

Answer:

1 and 3 are incorrect because white phosphorus cause phossy jaw disease and shoe chemiluminescence

Answer 2

X, an allotrope of phosphorus reacts with KOH to form hypophosphoric acid (Y) along with other products.

among these following 1 and 3 that is X does not show chemiluminescence and allotrope X is non- poisonous and insoulbel in water

Explanation:

1. White phosphorus is a toxic substance produced from phosphate-containing rocks. Industries use white phosphorus to manufacture chemicals used in fertilizers, food additives, and cleaning compounds. In the past, it was used as a pesticide and in fireworks.

2.white phosphorus show chemiluminescence because it is slowly oxidised at room temperature which emits the faint greenish glow.

3.In this chemical reaction if white phosphorus formation of excited reactive intermediate (PO)2 and HPO takes place which are responsible for emission of that faint greenish glow.
