In a reaction without a solvent, using 1-2 key peaks to justify what compound(s) that you think are present in your solid product would likely involve:
A) Monitoring the presence of functional groups in the infrared spectrum.
B) Analyzing the elemental composition using X-ray fluorescence spectroscopy.
C) Identifying specific chemical bonds through nuclear magnetic resonance spectroscopy.
D) Determining the crystal structure and lattice parameters using X-ray diffraction analysis.
