Name 3. Chapter 10 covered the synthesis of alkynes by a double dehydrohalogenation of dihalides. A student tried to convert trans-hex-2-ene to hex-2-yne by adding bromine across the double bord then doing a double elimination. The infrared and mass spectra are shown below. Bra 2 NaNH2 100 Relative Intensity Or 75 m/z a Do the spectra confirm the right product? If not what is it? b. Explain the important peaks in the IR. - Determine the structure using MS...

I need the answer for this questions step by step on a
document or a paper. It have to be clear so I can understand.
Please explain each answer. I will give thumbs up (like) to the
person that answer it correctly. Thank you.

Name: Starting with the mass spectrum of n-heptane What is the molecular ion? What fragment is lost to generate the ion with m/z =71? What cation does the peak at m/z = 43 represent? What group does the spacing between each set of ions represent? Why is the peak at (M-15), corresponding to loss of -CH3 so small?
