Introduction: The Grignard reagents are alkyl magnesium halides‚ R-Mg-X were first introduced in 1900. These reagents are usually prepared by reacting one atom with one molecule or by other means magnesium and alkyl halide in the presence of dry alcohol free ether.

because different substances require differing amounts of energy to evaporate. To test this‚ the temperature change from the evaporation of 4 different alcohols was measured and compared‚ along with cyclohexane. Methanol had the largest change in temperature‚ 18.9 ºC. This indicates that methanol has the weakest intermolecular attractions out of the 4 alcohols‚ because it evaporated the most. This may be because methanol is a small molecule so it has less electrons and therefore is not as polarizable as

by : Directorate of Education‚ Delhi SOME IMPORTANT REASONING BASED QUESTIONS OF ORGANIC CHEMISTRY 1. Chlorobenzene is less reactive than chloromethane. Ans. In chlorobenzene‚ each carbon atom of benzenering is sp2 hyridised and is electron withdrawing. Chlorine atom donates a lone pair of electron and acquire positive charge. The negative charge is delocalised on ortho and para position by resonance. C-Cl bond acquires partial double bond character and is 169 pm as compared to 17.0 pm in chloromethane

Brine shrimp and Ethanol research paper Ethanol is an alcohol substance that has effects on growth in organisms. Brine shrimp are used to tell the different levels of acidity in environments. Organisms absorb the substance around it; sometimes it has no effect on them sometimes it does. The best way to figure out if the environment has an acidity level too high for normal growth is to put the organism in a dish and watch carefully and observe any changes that occur in comparison to a normal organism

for Alcohol Consumption and whether it should be Raised Name of student: Name of instructor: Institution of affiliation: Date of submission: Legal Age for Alcohol Consumption Different governments have age limits for legal consumption of alcohol. For instance‚ in most western states individuals below 18 years of age should not consume alchohol. Other countries have an age limit of 15 years (Miller‚ 2010). All these governments have reasons for setting this age requirements for alcohol consumption

incidences are reported over the world every day due to alcohol consumption‚ such as drink driving‚ underage drinking and other health factors. I will summarize why alcohol product advertising should be banned with supporting evidence. II. Body A. Effects of advertisement 1. Advertisement is a powerful tool of producers to upswing the sale of the products. Example: Everyone watches TV almost every single day of their lives‚ thus come across alcohol advertisements. 2. Commercials alter peoples thinking

was to demonstrate the application of Zaitzev’s rule‚ the Evelyn Effect and the occurrence of an E1 mechanism in an alcohol dehydration reaction. Specifically this experiment involved the dehydration of 2-methylcylcohexanol by heating this alcohol in the presence of phosphoric acid and then to based on the results of the gas chromatography of the product to determine whether the alcohol exhibited the Evelyn Effect. The reaction taking place for both the Cis and the Trans isomers for Methylcyclohexanol
