- 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 (BUOK/ABUOH, 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.How many kinds of chemically non-equivalent hydrogens are there in each of the following compounds? a b a CH₂ CH-CH₂ b b CI-CH₂- xeview Toples] [References] How many kinds of chemically non-equivalent hydrogens are there in each of the following compounds?
