20. Suppose that you are given three colourless liquids whose identities are unknown. You are told that one is an alkane, one is an aldehyde, and one is a carboxylic acid. What property would you examine in order to differentiate between the liquids? Explain fully, using your knowledge of organic molecules and structures, how this property would allow you to distinguish between/ identify the compounds. (4A)

In an advanced analytical chemistry lab, a team analyzing a compound 'Q' known to be a structural isomer of octane (C8H18). 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
