The effect of the decrease in atmospheric pressure on the boiling point should be determined. Also, whether cyclohexane and toluene can be separated if the external pressure is 350 mm Hg instead of 760 mm Hg should be determined. Concept introduction: A technique used to separate various components or a fraction from a mixture based on their volatilities is called fractional distillation. The fractional distillation is used to separate different components of the mixture if boiling point difference is less than 75 ° C . Fractional distillation is better than the simple distillation due to the low boiling point range. It is used to separate crude oil into useful substances in oil refineries. The boiling point of the substance is that temperature value at which vapor pressure of the liquid is equal to the value of atmospheric pressure and the liquid changes into a vapor. It is a colligative property because it depends on a number of moles of solute particles that are present in the substance.

Predict the major products of this organic reaction: H OH 1. LiAlH4 2. H₂O ? Note: be sure you use dash and wedge bonds when necessary, for example to distinguish between major products with different stereochemistry. Click and drag to start drawing a structure. G C टे

For each reaction below, decide if the first stable organic product that forms in solution will create a new C-C bond, and check the appropriate box. Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below. Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first stable product you expect to form in solution. NH2 CI MgCl ? Will the first product that forms in this reaction create a new CC bond? Yes No MgBr ? Will the first product that forms in this reaction create a new CC bond? Yes No G टे
