- An organic compound has a percent composition, 89.84 %C, 10.17 %H. This compound has an approximate boiling point of 152 °C at 757 mmHg. The IR spectrum of the neat thin film is shown below.A 1.50 g sample of coniine, the toxic extract of poison hemlock, was dissolved in 10.0mL of ethanol and placed in a sample cell with a 5.00 cm pathlength. The observedrotation at the sodium D line was +1.21°. Calculate [α]D for coniine.c) FT-IR spectra of both nitro and nitrito-isomers were recorded immediately after preparation. Then small samples were exposed to heat (in oven) and their spectra were recorded again.
