Objective: To examine the use of a phase transfer catalyst to effect an SN2 reaction in dichloromethane solution. The reaction will be conducted without extraction for product isolation. List the procedural steps, from start to finish, that are required to convert 2-naphthol and allyl bromide into allyl 2-naphthyl ether. - The reaction is performed on a small scale by mixing the alcohol, the haloalkane, and the phase transfer catalyst in a conical vial. Sodium hydoxide (base) is added to ini...

Lab 1: Isolation of essential oils Why did we use steam distillation? - Steam distillation is used for temperaturesensitive compound which is immiscible in water. - In order to boil, the vapor pressure of liquid = vapor pressure of atm. Water and oil are immiscible. Therefore, they both contribute to vapor pressure. As a result, the mixture will start boiling at lower temperature than each of the compound does => we don't want to heat the mixture at the compound boiling point, it...

Separation by liquid-liquid extraction is based on a) compound's dielectric constant in 2 dif solvents b) # of theoretical plates in the separation c) use of phase transfer catalysts d) difference in boiling points of 2 liquids e) distribution of a compound between 2 immiscible phases - e) Distribution of a compound between two immiscible phases. Preparative gas chromatography is often chosen over distillation as a means of separation because gas chromatography a) is relatively inexpen...

Physical properties can be useful toDetermine structure Determine purity of substance If not pure, determine how to separate contaminating substances from a compound What can you get from melting point?Identify and purity of an organic solid. Define melting pointWhen the temperature at which the solid and liquid states are in equilibrium. What's the range at which most organic substances melt?50 - 250 C What's the range at which inorganic substances usually melt?300 - 1500 C What subs...

How should BP of a liquid be reported?As a boiling range How does temperature affect the vapor pressure of a liquid?As temperature increases, vapor pressure increases Suppose you will be distilling 50 mL of an impure liquid. What size of distillation flask(s) should you use?100 and 150 mL What is the purpose of using boiling stones?To relieve minor hot spots on the distillation flask and prevent vigorous eruption of bubbles (bumping) What should be the temperature difference in the liq...
