There are several isomeric alcohols and ethers of molecular formula C5H12O. Two of these exhibit the following 1H-NMR spectra. Propose a structure for each of the isomers.
Isomer A: δ = 0.92 (t, 7.8 Hz, 3 H), 1.20 (s, 6H), 1.49 (q, 7.8 Hz, 2H), 1.85 (s, 1H) ppm
Isomer B: δ = 1.19 (s, 9 H), 3.21 (s, 3H) ppm
An aromatic compound K, whose molecular formula is C8H11N, is examined in the laboratory to elucidate its structure. The following observations were made:
A) Compound K is soluble in dilute hydrochloric acid but insoluble in sodium hydroxide solution.
B) Treatment of compound K with excess potassium hydroxide and benzenesulfonyl chloride, C(6)H(5)SO(2)Cl, results in the formation of a heterogeneous mixture. The NMR spectrum of compound K is shown below.
C) Compound K when treated with acetic anhydride[CH3-C(O)-O-C(O)-CH3], gives compound L, whose molecular formula is C(10)H(13)ON. Compound L is insoluble in dilute acid or dilute base at room temperature, heating compound L in dilute acid or base, however, regenerates compound K.
D) When compound L is heated with a mixture of concentrated nitric acid and sulfuric acid, a single product, compound M, with the molecular formula C(10)H(12)O(3)N(2) is formed in excellent yields.
On the basis of these observations draw the structures of…

- y-Butyrolactone (C4H6O2, GBL) is a biologically inactive compound that is converted to the biologically active recreational drug GHB (Section 19.5) by a lactonase enzyme in the body. Since y-butyrolactone is more fat soluble than GHB, it is more readily absorbed by tissues and thus produces a faster onset of physiological symptoms. y-Butyrolactone shows an absorption in its IR spectrum at 1770 cm-1 and the following 1H NMR spectral data: 2.28 (multiplet, 2 H), 2.48 (triplet, 2 H), and 4.35 (triplet, 2 H) ppm.
