c) An unknown chiral organic compound with molecular formula C7H1402 has a characteristic IR absorptions at approximately 3000 cm 1, 1715 cm-1, 2400 - 3400 cm 1 (broad absorption) and 1250 cm1. Propose a possible structure of this unknown compound.

Determine: The number and placement of the carbon chirality centers, if any. If this structure can have an enantiomer, why? What is the configuration of the highlighted carbon and how did you determine that?

Propose a structure consistent with each set of data. C8H10 : IR absorptions at 3108–2875, 1606, and 1496 cm−1

Identify the structures A, B, C, D, E, and F name them, and draw the absolute configuration if there is any

The 'H NMR spectrum of compound A (C3H100) has four signals: a multiplet at 8 = 7.25-7.32 ppm (5 H), a singlet at d = 5.17 ppm (1 H), a quartet at d = 4.98 ppm (1 H), and a doublet at ô = 1.49 ppm (3 H). There are 6 signals in its 13C NMR spectrum. The IR spectrum has a broad absorption in the -3200 cm-1 region. Compound A reacts with KMNO4 in a basic solution followed by acidification to give compound B with the molecular formula C7H6O2. Draw structures for compounds A and B.
