Question

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

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

Answer 1

The correct option is A are both soluble in ${\text{CS}}_2$

Red and white phosphorous oxided by heating in the presence of air.
Red phosphorus is insoluble in ${\text{CS}}_2$ and only white $\text{P}$ is soluble in ${\text{CS}}_2$.
Red phosphorus can be converted to white phosphorus by careful heating
