In an advanced analytical chemistry lab, a team is analyzing a compound 'Q' known to be a structural isomer of octane (CH). To determine the specific structure of 'Q', a series of spectroscopic analyses are performed. The sequence of the analysis involves: Infrared (IR) spectroscopy, which indicates the absence of functional groups like alcohols, ketones, and carboxylic acids. Nuclear Magnetic Resonance (NMR) spectroscopy, showing signals indicative of only methyl and methylene groups, with no evidence of methine (CH) or quaternary carbon environments. Mass spectrometry (MS), revealing a fragmentation pattern consistent with branched alkane structures. Based on this sequence of analyses, what is the most likely structure of compound 'Q'? Options: A. 2,2,4-Trimethylpentane B. n-Octane C. 2-Methylheptane D. 3-Ethylhexane Don't use chatgpt please provide valuable answer
