Lecture 14 Reduction Reactions 2.1.1 Lithium Aluminum Hydride (LAH) 2.1.1.1 Introduction Lithium aluminum hydride (LAH) is a strong reducing agent with chemical formula LiAlH4. It can reduce a variety of functional groups such as aldehydes‚ esters‚ acids‚ ketones‚ nitriles‚ epoxides and azides. It vigorously reacts with water and all the reactions are performed in polar aprotic solvents. 2.1.1.2 Preparation It was first prepared by treating lithium hydride (LiH) with aluminum chloride (AlCl3)

Cell phone batteries die and when they do‚ it is very easy to recharge it. All you do is find an outlet‚ plug it in‚ and charge your phone. Everyone is very cautious about their phone’s battery percentage but why not about their car’s. It is very common that one day you will find yourself needing a jump start to your car. The average battery life of a car last between 2 and 5 years. Signs of a dead battery are; the car not starting‚ beeping when you try to start the car‚ and the battery icon near

She worked extremely hard and never let the racism in the eighties and nineties put her down; she just kept going she had a lifetime amount of fuel like she was powered by a rechargeable battery. Eventually it all paid off and she became a very successful accountant. This fills me ambition to follow in her footsteps and not let obstacles I encounter hold me back. If there was anybody that spent the most memories with me‚ it was my grandma

basically a rechargeable battery. It is used to absorb electric energy from a source‚ store it as kinetic energy of rotation‚ and then deliver it to a load at the appropriate time‚ in the form that meets the load needs. A typical system consists of a flywheel‚ a motor/generator‚ and controlled electronics for connection to a larger electric power system .Flywheels are not affected by temperature changes as are chemical rechargeable batteries‚nor do they suffer from memory

Discussion: In this experiment a ketone‚ 9-fluorenone is reduced to and alcohol. The are two possible ways by which this reduction can occur. One is by a catalytic hydrogenation‚ this uses a catalyst such as palladium or nickel‚ hydrogen gas‚ and heat/pressure. This can reduced an alkane to alkene. This catalytic process is preferred in industrial practices because the cost is low in the long run and more importantly there is little to no waste expense. However‚ hydrogen gas is dangerous due to
