useful in synthesizing various types of alkenes with unique properties. This elimination process could simply be used to synthesize other alkenes for industrial or lab purposes. More specifically‚ alkenes are used in the polymerization of plastics. Ethanol can be dehydrated to ethene. Polyethene is used in the manufacturing of raincoats‚ shoe soles‚ pipes‚ and floor tiles (Preserve

Although alcohol is sometimes seen as a recreation‚ it is truly a deadly substance. To start‚ by prohibiting alcohol‚ it will prevent the physical symptoms of alcohol. Also‚ by making alcohol unauthorized for consumption‚ people will also be avoiding health problems. In addition‚alcohol contains hazerdous chemicals that are unhealthy towards humans.To add‚ alcohol also has a numerous amount of non-benefits toward human nutrients consumption. To sum up‚ by making alcohol unauthorized for consumption

Indian liquor industry – Regulatory hangover to continue The Indian liquor industry is a high-risk industry‚ primarily on account of the high taxes and innumerable regulations governing it. As a result‚ liquor companies suffer from low pricing flexibility and have inefficient capacities‚ which‚ in turn‚ have led to low margins and weak financial profiles. Moreover‚ even though the two large liquor groups in the country enjoy a majority market share‚ the price-sensitive nature of the industry

Introduction: In the lab‚ Bromide was combined with trans-cinnamic acid in order to see if the resulting product at the end of the experiment would yield either an erythro- or threo-dibromide. Based on how well this experiment was done there is a possible product that would have a melting point around 95°C‚ threo-‚ 205°C‚ erythro-‚ or somewhere in the middle which would be a combination of the two. The process of refluxing was used to purify the mixture followed by crystallization. In the end
