Q1: Which product is formed when benzene reacts with isobutyl chloride in the presence of AlCl3? Q2: How many signals will appear in an 1H-NMR spectrum for (1R,3S)-1,3-dinitrocyclopentane?
A1: It forms tert-butylbenzene A2: There will be five signals in the proton NMR.
When ethene (C2H4) reacts with water vapor, ethanol (C2H6O) is produced. If an equilibrium mixture contains 0.020 M C2H4 and 0.015 M H2O, what is the equilibrium concentration of C2H6O? At 327 degrees Celsius, the Kc is 9.0x10^3.
The equilibrium concentration of ethanol is 2.7 M.

Explain the difference between the instruments in categories A, B, and C according to SWGDAM.
Category A instruments are those that provide identification such as FTIR and mass spectrometry Category B instruments are those that are considered separation instruments or techniques. These include gas chromatography, thin-layer chromatography, high performance liquid chromatography, and ion chromatography. Category C instruments are presumptive tests such as UV-vis and fluorescence instrumentation.
