Question

Which one of the following forms of

phosphorus is most reactive?

A. Black phosphorus

B. White phosphorus

C. Violet phosphorus

D. Red phosphorus​

Answer 1

Ans. B

Sol. Phosphorus is a chemical element

with symbol P and atomic number

15. As an element, phosphorus

exists in two major forms—white

phosphorus and red phosphorus—

but because it is highly reactive,

phosphorus is never found as a free

element on Earth. At 0.099%,

phosphorus is the most abundant

pnictogen in the Earth's crust. With

few exceptions, minerals containing

phosphorus are in the maximally

oxidized state as inorganic

phosphate rocks. Phosphorus

occurs in at least 10 allotropic

forms, the most common (and

reactive) of which is so-called white

(or yellow) phosphorus which looks

like a waxy solid or plastic. It is very

reactive and will spontaneously

inflame in air so it is stored under

water.

Answer 2

Answer:

the correct answer is option B

white phosphorus is most reactive .
