An allotrope of phosphorous, exhibits a phenomenon of phosphorescence, produces compound 'A' which on reacition with O_(2) gives 'B'. The number of oxygen atoms bonds to each central atom in 'A' and 'B' are 'X' and 'Y' respectively. When 'A' is heated to 210^(@)C it decomposes to an oxide 'D' and another allotrope of phosphorus 'C'. This allotrope of phosphorous reacts with halogens to produce the pentahalides but nitrogen does nto give pentahalides. The reason is:
