Lañez‚ Kristine Department of Psychology College of Science University of Santo Tomas España Manila 1015 Abstract A hydrocarbon is strictly composed of carbon and hydrogen atoms only. Five hydrocarbons were used namely hexane‚ cyclohexene‚ toluene‚ naphthalene (in hexane)‚ and the unknown (which will be known through parallel chemical tests). Three tests‚ nitration test‚ bromine test and basic oxidation test were conducted to fully differentiate each type of hydrocarbon from one another. Nitration

The Separation of a Liquid Mixture by Simple Distillation Objective The purpose of doing this experiment is to separate two miscible liquids samples of cyclohexane and toluene using simple distillation. The objectives will be to record boiling range and volumes (mL) of distillates that are attained during the process of distillation. Background Distillation is a frequently used technique for separating mixtures based on differences in the boiling points of components in the mixture. The

halogenation reaction. If the bromine reacted with the alkene the bromine would discolor from orange and turn clear. Experiment Part A) Solubility of Alkanes: 1 mL of nine solvents (water‚ methanol‚ n-butanol‚ ethylene‚ glycol‚ acetone‚ hexane‚ toluene‚ ethyl acetate‚ and dichloromethane.) was added to nine sample vials. Each vial then had 0.5 mL of the alkane decalin added to each one. The mixtures were stirred to determine if the materials dissolved. If the material was insoluble it was heated

Abstract The aliphatic and aromatic hydrocarbon are can be differentiate by .For example‚in the experiment involving aliphatic hydrocarbon which is cyclohexane that undergo the reaction with bromine water in the presence of UV light.This reaction is known as substitution reaction.The cyclohexane that react with bromine under present of UV light will change to slightly brown while the other one has no changeous which is still brown.For baeyer’s test‚the alkane which is heptanes will not undergo the

combination of the mixture. The addition of a fractionating column allows numerous small distillations to occur within the column as the vapour rises towards the condenser. This experiment will demonstrate the separate a 50:50 mixture of toluene and cyclohexane by two methods and will require two separate equipment setups - one with the fractionating column (fractional distillation) and condenser and one with only the condenser (simple distillation). The results will show the contrast between the
