27. You've been given an unknown alkane in the lab (compound X) its molecular formula is C7H16. When reacting X with Br2/hv, three different products are formed: A, B and C. A and B are were each reacted separately with NaOEt/EtOH and you find that they both give the same product, D (C7H14, 'H NMR on next page). When C reacts with tBuOK/tBuOH, E is formed (C7H12, 'H NMR on next page). E can then react with ethylene and heat to form the Diels-Alder product F (given). compound F Provide structures for X, A, B, C, D, and E in a clearly labeled roadmap/reaction scheme in the space below. Then, label the NMRS on the next page with proper assignments using a clear lettering system for compounds D and E.
Analyzing Infrared Spectra
The electromagnetic radiation or frequency is classified into radio-waves, micro-waves, infrared, visible, ultraviolet, X-rays and gamma rays. The infrared spectra emission refers to the portion between the visible and the microwave areas of electromagnetic spectrum. This spectral area is usually divided into three parts, near infrared (14,290 – 4000 cm-1), mid infrared (4000 – 400 cm-1), and far infrared (700 – 200 cm-1), respectively. The number set is the number of the wave (cm-1).

IR Spectroscopy
Infrared (IR) or vibrational spectroscopy is a method used for analyzing the particle's vibratory transformations. This is one of the very popular spectroscopic approaches employed by inorganic as well as organic laboratories because it is helpful in evaluating and distinguishing the frameworks of the molecules. The infra-red spectroscopy process or procedure is carried out using a tool called an infrared spectrometer to obtain an infrared spectral (or spectrophotometer).
In the given problem, an alkane X having a molecular formula of undergoes the bromination reaction in the presence of sunlight to form three products mainly A, B and C. The compound A and B on treating with NaOEt in the presence of EtOH will yield a same product namely D with molecular formula while the compound C on reacting with NaOEt in the presence of EtOH will yield a product E with molecular formula .
The product E formed will reacts with ethylene to give Diels elder product F whose structure is given in the question.
