Introduction: The technique used to separate an organic compound from a mixture of compounds is called Extraction. Extraction process selectively dissolves one or more of the mixture compounds into a suitable solvent. The solution of these dissolved compounds is referred to as the Extract. Here the organic solvent dichloromethane is used to extract caffeine from an aqueous extract of tea leaves because caffeine is more soluble in dichloromethane (140 mg/ml) than it is in water (22 mg/ml). However, there are...

2. Identify the strongest type of intermolecular forces in acetone, ethanol, water and hexane. (Structures listed on page 15.) Experiment 2 Intermolecular Forces There are three general types of intermolecular forces. All substances exhibit London Dispersion Forces (LDF), and they are generally the weakest of the three types. These London forces are due to the attractions between small, temporary dipoles that arise from the constant, random movement of the electrons in a substance. As molar mass increases, the size of...

Question to answer from the lab: What aspect(s) of the approach taken is/are NOT especially green? What changes might be made to make the overall process greener? The Lab Experiment Summary Polyethylene glycols such as PEG-400 are currently of great interest to organic chemists, since their application as reaction solvents is very intriguing (1). PEG-400 is non-volatile and nonflammable in nature, and also possesses important properties such as recyclability, ease of work-up, thermal stability and economical cost. In addition, the...

Grignard Reaction 1. Draw your complete reaction, including the formation of the Grignard reagent and the reaction with your carbonyl compound. Below each reagent, write its molecular weight and density (if a liquid). Also write how much of each material you will use in ml (if liquid), grams, and moles. Also include the molecular weight and melting point of your final product. 2. How many moles of Grignard reagent are you synthesizing? What mass of water could fully react with...

Process A. Preparation of 4-t-butylcyclohexene Assembling the equipment Fill the almost complete sand bath, place it on the base of the shelf, fix the thermometer with a clip and start heating until the temperature of the sand is - 110C. B. Mixing the reagents Using the plastic funnel, introduce 0.60-0.70 g of 4-t-butylcyclohexanol into a large, clean, dry test tube. Then add 10 drops of concentrated phosphoric acid, 3 drops of concentrated sulfuric acid and a pebble to moderate boiling....

1. Introduction In recent years, nanoclays have been the object of particular interest for many scientists and researchers in chemistry, physics, engineering and biology due to their excellent properties as well as their sustain- ability [1-3]. For instance, they represent the starting point to the de velopment of smart materials for drug delivery (4-9), food packaging [10-12), environmental remediation and wastewater treatment [13], cultural heritage [14–17and...
