State flammable gas and a are formed

Reference no: EM13172228

The mass spec of a yellow, diamagnetic solid A, a neutral metal carbonyl, reveals a molecular ion peak of 390 amu. A fragmentation pattern consisting of sequential losses of 28 amu (CO) occured until m/z = 110 amu. Consider the following conditions: -Treatment of A with Cl2 affords 2 mols of white crystalline solid B whose IR spectrum is similar to A - Treatment of A with Na(Hg) in THF affords 2 mols of air-sensitive salt C. - Reaction of C with H3PO4 gives colorless D. NMR of D exhibits resonance at -4 ppm. - On heating D, a flammable gas and A are formed. - Reaction of C with CH3I affords white solid E whose proton NMR shows a single resonance around 0.2 ppm. Identify A-E.
