Nucleophilic Substitution | Synthesis of n-Butyl Bromide and t-Pentyl Chloride | | Jessica | [Pick the date] | Abstract The synthesis of the alkyl halide n-Butyl Bromide from alcohol is the foundation for the experiment. During the isolation of the n-butyl bromide‚ the crude product is washed with sulfuric acid‚ water‚ and sodium bicarbonate to remove any remaining acid or n-butyl alcohol. The primary alkyl halide halide n-butyl bromide is prepared by allowing n-butyl alcohol to react with

Alkenes by Elimination Kyle Peterson Chem. 243a Matt Judd‚ Sec. 25 Date Performed: 11/12/03 Abstract: The objective of this experiment is to successfully perform a dehydration of a 2-butanol and a dehydrohalogenation of 2-bromobutane to form the products 1-butene‚ trans-2-butene‚ and cis-2-butene. It was found that a dehydration of 2-butanol yielded 4.6% 1-butene‚ 67.3% trans-2-butene‚ and 28.1% cis-2-butene‚ and a dehydrohalogenation of 2-bromobutane yielded 19.1% 1-butene‚ 69.9% trans-2-butene

Labour essay: Having considered the implications for the WTC‚ we can now analyse the effects of the policy on labour supply by determining the substitution and income effects. It’s clear that the effect of the working tax credit on work behaviour depends upon how much a worker is currently working. To analyse these effects we will only look at one type of individual; a lone parent in the labour force. This will simplify our analysis such that we can divide the diagram below into 3 sections

“Knowledge is not the key” –Dan Ariely http://www.youtube.com/watch?v=XkfYDhZGAVE “When we think about human behavior‚ we often think that people are motivated by big visions‚ but the reality is that those things influence are wishful thinking‚ but they rarely influence are actual behavior. And because of that‚ there’s a gap between what we know what we should be doing and what we actually do.” “Telling people what’s the right thing to do in principle is just not the right way to do anything

Many countries have adopted different development strategies in order to promote growth. One of these‚ used by the now developed economies following the Industrial Revolution‚ is import substitution industrialisation (ISI). This is the notion of reducing foreign dependency of a country’s economy through focusing on domestic production of goods and services. An opposing strategy is export promotion. This includes measures taken by the government to increase the quantity and variety of goods and services

Tricarbonylchromium Derivatives of Aromatic Compounds. By B. NICHOLLS M. C. WHITING. and Many aromatic compounds‚ ArH‚ displace carbon monoxide from chromium hexacarbonyl with the formation of complexes Cr(CO)‚(ArH) (I). These are stable and may carry any of several functional groups. The effects of the metallic residue upon typical properties of these groups and of the aromatic system as a whole are outlined‚ and methods for the regeneration of the aromatic components are described.

Substitution Reactions of Molybdenum Hexacarbonyl and the Use of Infrared Spectroscopy as a Structural Tool 01-09-2011 Abstract A variety of metal carbonyl derivatives can be synthesized by substitution reactions. In this experiment two geometric [Mo(CO)4(PPh3)2] isomers A and B were synthesized and their molecular geometries were determined by means of infrared spectroscopy. Isomer A was synthesized first by reacting [Mo(CO)6] with sodium borohydride employed as a reducing agent and triphenylphosphine

What factors propelled many countries to implement Import Substitution Industrialisation? To what extent did the strategy succeed in helping economies to boost growth rates and to overcome balance of payments constraints? According to Braer‚ ‘import substitution and industrialisation is an attempt by economically less developed countries to break out of the world division of labour. (Braer 1972)‚ This division of labour meant that the developing nations from Latin America‚ Africa and East Asia
