- When compound A (C5H12O) is treated with HBr, it forms compound B (C5H11Br). The 1H NMR spectrum of compound A has a 1H singlet, a 3H doublet, a 6H doublet, and two 1H multiplets. The 1H NMR spectrum of compound B has a 6H singlet, a 3H triplet, and a 2H quartet. Identify compounds A and B.arrow_forwardIdentify the structure of compound C (molecular formula C11H15NO2), which has an IR absorption at 1699 cm−1 and the 1H NMR spectrum shown below.arrow_forwardHh.63.arrow_forward
- Compound A undergoes an acid-catalyzed hydrolysis. One of the products (B) that is isolated gives the following 1H NMR spectrum. Identify the compounds A and Carrow_forwardCompound A, MW 72, shows an IR absorption at 1711 cm-1 and a 1H NMR spectrum with peaks at 2.4 8 (2 H, quartet), 2.1 8 (3H, singlet) and 1.1 8 (3 H, triplet). Propose a structure for A. Drawingarrow_forwardConsider carbonyl compounds A–E drawn below. (a) Rank A–E in order of increasing stability.
