1.	Which allotrope of phosphorus does not catch fire easily?(a) White phosphorus(b) Alpha- black phosphorus(c) Beta- black phosphorus(d) Red phosphorusI had been asked this question during an interview.Enquiry is from P-Block Elements topic in section P-Block Elements of Chemistry – Class 12
Answer» Right choice is (d) Red PHOSPHORUS The explanation: Red phosphorus is a relatively stable ALLOTROPE of phosphorus at ROOM temperature. Its ignition temperature(543 K) is much higher than that of white phosphorus(303 K). As a result, it does catch fire easily.
