Question Description
Direction (Q. Nos. 14and 15) This section contains a paragraph, describing theory, experiments, data, etc. Two questions related to the paragraph have been given. Each question has only one correct answer among the four given options (a), (b), (c) and (d).PassagePhosphorus was discovered by Brand (1669), Scheele isolated from bone ash and Lavoisier proved its elemental nature (1777). The principal minerals are phosphate rock, fluoroapatite and chloroapatite. Phosphorus is prepared by the direct reduction of phosphorite by carbon in the presence of silica. It exists in different allotropic forms such as yellow or white, red, α-black, β-black, etc. White P is most reactive, poisonous, glows in dark and readily catches fire due to unstable discrete P4 molecules. Red P is inert, non-poisonous, does not glow etc., due to its polymeric structure, α-black, β -black allotropes are also chemically inert, do not ignite at normal temperature. It has layer structure like graphite and acts as conductor.Q.The allotrope of phosphorus with low ignition temperature isa)white Pb)red Pc)α-blackd)β-blackCorrect answer is option 'A'. Can you explain this answer? for Class 12 2024 is part of Class 12 preparation. The Question and answers have been prepared according to the Class 12 exam syllabus. Information about Direction (Q.
