Discussion & Error Analysis: By examining the unknown alcohol’s H NMR spectra‚ it can be deduced that the alcohol is 1-(3-methoxyphenyl)ethanol. There are three peaks that have a shift of ~7.0-7.5‚ one with integration values of 1‚ 2‚ and 1.This shows that the alcohol is a meta-substituted benzene ring. The singlet peak with a chemical shift of~ 4.7 ppm with an integration of 1 is from the hydrogen on the OH group. The peak at ~ 1.7 ppm corresponds to the hydrogen of the carbon that is attached

distillation‚ the percent ethanol and percent loss of 15 mL of vodka was computed. The calculations were supported by a flammability test. With the distillation process reaching 100oC‚ 6.0 mL of distillate was collected. The determination of ethanol from the distillate was conducted through the flammability test‚ which resulted to 4.5 mL. After the needed computations‚ it was measured that the percent ethanol was 30% and the percent loss was 26%. Keywords: simple distillation‚ percent ethanol‚ percent loss

An alcoholic beverage is a drink containing chemicals from the alcohol family. Mostly ethyl alcohol (ethanol‚ EtOH)‚ other alcohols are usually present only in small quantities‚ notably consumable t-Amyl alcohol (t-Amylol‚ t-AmOH) which is about 20X more potent than ethanol‚ and hazardous methanol with much weaker sedative effect than ethanol‚ thus are not prohibited by law or regulated by taxation in most if not all countries. However‚ alcoholic beverages are divided into three general classes for
