Engineering Chemistry III Prof. K. M. Muraleedharan Aromatic electrophilic substitution (Ar-SE) Reactions The special reactivity of aromatic systems towards electrophiles arises mainly from two factors: the presence of π electron density above and below the plane of the ring - making it nucleophilic‚ and the drive to regain the aromatic character by opting for substitution as opposed to a simple addition reaction. Preference towards addition reactions in the case of alkenes and substitution

680cc-flame. The magnetic susceptibility values were obtained at room temperature using Magnetic Susceptibility Balance Bruke Magnet B.M.6. The 1H and 13C nuclear magnetic resonance spectra were recorded on a jeol 400 MHz spectrometer in dueteated DMSO‚ relative to the internal standard Tetramethylsilane (TMS). Conductivity measurements were carried out by using a WTW conductivity meter . Synthesis of Ag (I) complexes A solution of (2.5 mmole) of AgNO3 dissolved in 50 ml of water was added drop by

In order to determine the acidity of certain substances‚ we used moist and dry pH paper (litmus tests)‚ and observed the results. First we used dry pH paper to test the acidity of household ammonia‚ and it turned yellow. According to the legend‚ this indicates a weak acid. This is‚ however‚ not accurate as the vapor of the household ammonia wasn’t able to react as strongly with the pH paper since it was dry. Then‚ we used moist DI water pH paper with the same substance‚ household ammonia‚ and it

produces a lot in Spain with exclusive suppliers‚ it give to Zara a great reactivity and a good control. Zara reduces also inventory risk and delays thanks to limited series. Zara is able to deliver all of its stores since their huge warehouse which centralized the production‚ it limits intermediaries‚ reduce stocks‚ and delays. One of the main difference between Zara and H&M is that H&M has not the quickness‚ the reactivity of his production tool and the short delays that Zara can have because H&M

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
