Abstract A Friedel-Crafts alkylation was performed by adding t-butyl alcohol to p-dimethoxybenzene in order to produce 1‚4-di-t-butyl-2‚5-dimethoxybenzene. This reaction yielded 0.009g of 1‚4-di-t-butyl-2‚5-dimethoxybenzene having a percent yield of 5%‚ and a melting point range of 54.8°C-56.9°C. Introduction This reaction is designed to put functional groups onto aromatic rings. This is done through an electrophilic aromatic substitution where a positive species is strong enough to pull electrons

Introduction: Stillnox has many different names‚ Zolpidem‚ Ambiem and Lorex to name a few. Zolpidem is a prescription drug used for treating insomnia‚ it works quickly (within 15 minutes) and the effects last for around 3 hours (PubChem‚ 2016). As Stillnox is extremely effective in helping insomnia sufferers fall asleep a Stillnox dependence occurs and can often lead to addiction. In extreme circumstances death from overdose of Stillnox has and can occur. This can affect society in a number of different

Shift Analysis The Nuclear Independent Chemical Shift is measured as magnetic shielding of a molecule have been calculated at the B3LYP/6-31G theory level. Aromaticities are represented by negative NICS Values and antiaromaticity is represented by positive NICS Values. The large negative NICS Values of the title compound represent stronger aromaticity [29-35].Our present investigation of the density functional calculations of doped fullerene with glycine shows several lines at different positions can

Miscibility of the test compounds were noted through color change or a warming effect. Flammability was tested by igniting 3-5 drops of the sample in a small evaporating dish. Baeyer’s test and Bromine test were used for tests for active unsaturation. Aromaticity of the compound was determined through nitration. Oxidation was tested by introducing 8 drops of 2% KMnO4 solution and 3 drops of 10% NaOH solution to 4 drops of the sample organic compound in a test tube and warming the mixture through water bath

Phenol‚ also known as carbolic acid‚ is an aromatic organic compound with the molecular formula C6H5OH. It is a white crystalline solid that is volatile. The molecule consists of a phenyl group (-C6H5) bonded to a hydroxyl group (-OH). It is mildly acidic‚ but requires careful handling due to its propensity to cause chemical burns. Phenol was first extracted from coal tar‚ but today is produced on a large scale (about 7 billion kg/year) from petroleum. It is an important industrial commodity as a
