- 1) They were given a mysterious chemical by ASP Rinuprasad, coded as Compound X, which was believed to be a forbidden drug smuggled through KLIA airport. Little they know about the chemical from the convict. As competent officers, together they decided to run several spectroscopic and analytical tests to determine the molecular structure of Compound X. They managed to obtain the spectra and data of IR, 'H NMR (400 MHz in CDCI 3), 13C and DEPT (100.6 MHz in CDC13), COSY, HMQC, HMBC, mass spectrometry and elemental analyses. Determine the molecular structure and name of Compound X.
