3. Elemental analytical data for a new, monomeric compound X is a requirement of publishing details of the compound in the literature, even when crystallographic and spectroscopic data are available. This is because: (A) elemental analysis is a requirement purely for historical reasons (B) elemental analysis is the only method of confirming that the compound contains no solvate (C) elemental analysis confirms the composition of the bulk sample (D) elemental analysis confirms that the compound is a monomer and not a dimer or higher oligomer
