Question

Each of the following is true for white and red phosphorus except that they:

• A. are both soluble in $C{S}_2$
• B. can be oxidized by heating in air
• C. consist of the same kind of atoms
• D. can be converted into one another.

Answer 1

Answer: (A)

are both soluble in $C{S}_2$

White phosphorus, yellow phosphorus or simply tetraphosphorus ($P_4$) exists as molecules made up of four atoms in a tetrahedral structure. As phosphorous molecule is non polar,so it dissolves in non polar solvent like carbon disulfide, $C{S}_2$.

Hence option A is correct.
