Question

Red phosphorus is more stable than white phosphorus because :

• A. its melting point is high
• B. of its colour
• C. it has strong bonds in its atoms
• D. all of the above

Answer 1

The correct option is C it has strong bonds in its atoms

Red phosphorous is polymeric in structure. There is one additional bond formed in phosphorous tetrahedron resulting in chain structure. White $P$ is the least stable,the most reactive,the most volatile and gradually changes to red $P$. This is accelerated by light and heat.
