Question

Phosphorus is found in many allotropic forms. Consider the conversion of X allotropic form to Y allotropic form

$X\underset{\text{in an inert at most here for several days}}{\overset{573K}{\to }}Y$

Select the correct statement with respect to X and Y.

• A. Both X and Y are insoluble in water but soluble in $C{S}_2$
• B. Y is thermodynamically most stable allotrope of phosphorus
• C. X is thermodynamically more stable than Y
• D. In the structure of X and Y each phosphorus atom is attached to three other phosphorus atoms

Answer 1

The correct option is D In the structure of X and Y each phosphorus atom is attached to three other phosphorus atoms

X - White phosphorus
Y - Red phosphorus.
