Question

White phosphorus can be reconverted to red phosphorus.

(a) True

(b) False

This question was addressed to me by my college director while I was bunking the class.

The doubt is from P-Block Elements in section P-Block Elements of Chemistry – Class 12

Answer 1

Right choice is (a) True

Explanation: Yes, red phosphorus sublimes on heating giving vapours which are the same as by white phosphorus. When these vapours are condensed, white phosphorus is obtained. This gives us simple method of reconverting red phosphorus into white phosphorus.
