NPTEL – Chemistry – Reagents and Organic reactions Module II 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

| Distillation is defined as: `Distillation is based on the fact that the vapor of a boiling mixture will be richer in the components that have lower boiling points.Therefore‚ when this vapor is cooled and condensed‚ the condensate will contain more volatile components. At the same time‚ the original mixture will contain more of the less volatile material. Distillation columns are designed to achieve this separation efficiently.Although many people have a fair idea what “distillation” means‚ the

the sulfanilamide was dissolved in the mother liquor‚ and also because of a small spillage of the crystals from the filtration step. Part C of this lab was performed by first finding the best solvent for Fluorene. This was done by testing water‚ toluene‚ and methyl alcohol by adding 6mL of solvent to .3g of Fluorene. It is then shaken‚ if it dissolves immediately like it did

Infrared Spectroscopy Organic Chemistry Lab 301A B. The purpose of this lab is to study Infrared Spectroscopy‚ which focuses on the study of the electromagnetic spectrum. The area to be studied is the infrared region‚ which is made up of gamma‚ X‚ and UV rays. We want to be able to identify spectra’s to their complementary structures. The background of this experiment particularly deals with the study of compound structure determination‚ and traits. We must be aware of the functional groups

investigation along similar lines to the work you did on the chlorides of the elements in Period 3 (Experiment 4.12). However‚ you will not be asked to test the oxides with cyclohexane because unlike the covalent chlorides‚ most of the oxides are not composed of discrete molecules. Therefore they are unlikely to dissolve in cyclohexane and simple experiments cannot distinguish between insolubility and slight solubility.

trying to convert a decimal number which has a fractional part? First we can see that it is obvious that the integral part of a decimal number will always be represented by an integral binary (with no fractional part) while the fractional part of a decimal number will always be represented by a fractional part of a binary number (with no integral part). An integral number will be integral in any integral base and a fractional number will be fractional in any integral base. This means we can split
