Question:

Using the following information, propose structures for each of these compounds. 

(a) C5H10O, NMR spectrum A, UV λmax(e) 5 280(18) nm; 

(b) C5H8O, NMR spectrum B, UV lmax(e) 5 220(13,200), 310(40) nm; 

(c) C6H12, NMR spectrum C, UV lmax(e) 5 189(8,000) nm; 

(d) C6H12O, NMR spectrum D, UV lmax(e) 5 282(25) nm. 

3 H 3 H 3 H T 2.4 1.6 0.9 3 H 2 H 2H 6.9 6.8 6.7 6.6 6.5 6.4 6.3 6.2 6.1 (CH3)4Si (CH3)4Si 1 H 1 H 3.0 2.5 2.0 1.5 1.0 0.5 0.0 7.0 6.5 6.0 5.5 5.0 4.5 4.0 3.5 3.0 2.5 2.0 1.5 1.0


Next, for each of the following reactions, name an appropriate reagent for the indicated interconversion. (The letters refer to the compounds giving rise to NMR spectra A through D.) (e) A → C; (f) B → D; (g) B → A.
