1. For each of the following statements, indicate whether they are true of false. ⚫ mass spectrometry allows us to determine the molar mass and molecular formula of an organic compound, as well as some of its structural features. • mass spectrometry generally allows us to determine the precise structure of an organic compound. ⚫ when a molecular ion undergoes fragmentation, weak bonds break in preference to strong bonds. • when a molecular ion undergoes fragmentation, bonds that break to form less stable fragments break in preference to those that form more stable fragments. • the only way to ionize an organic compound is by passing it through a beam of 70 eV electrons. • mass spectrometry is one of several techniques that are routinely used for the determination of the structure of an unknown organic compound. • mass spectrometry can be coupled with gas chromatography to afford a very valuable separation/analysis technique. • chlorides and bromides are dead easy to spot because of the…

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

C5H12 has 3 structural isomers C6H14 has 5 structural isomers C7H16 has 9 structural isomers. I get what a structural isomer is, but when I see a statement like the 3 statements above, I wonder if there is a way I can figure out how many structural isomers something has?  I'm in CHEM 2.  We didnt talk about that but when I see a slide he has telling me this, and I am wondering what to take from the slide...hmmm.

Break open your cyclohexane ring to make n-hexane (C6H14). (You will need two extra hydrogen atoms to the terminal carbon atoms to complete your model). Is hexane flexible or rigid? The melting point of cyclohexane is 6o C whereas the melting point of hexane is -94o C. Can you suggest a reason for this based on the structures you have made?
