a colourless solid.
a chloro and nitro substituted aromatic compound.
Extra element(s) - nitrogen, halogen(s). Absent - sulfur.
Present are one or more fuctional groups like amines, amides, cyanides, nitro compounds (nitrogen containing), alkyl, aryl or acyl halides (halogen containing). Use the mass spectrum to determine the halogen(s).  Absent are functional groups like sulfonic acids (sulfur containing), sulfonamides (sulfur and nitrogen containing).
