Experimental Synthesis of Bupropion – A round bottom flask (RBF) containing m-chloropropiophenone (1.0 g‚ 5.9 mmol) dissolved in 5.0 mL dichloromethane (DCM) with 0.25 mL of 1.0 M Br2 in DCM was briefly warmed to initiate the bromination reaction. Afterwards‚ the RBF was placed in and ice-water bath and 1.0 M Br2 in DCM (6.0 mL‚ 6.25 mmol) was added dropwise while stirring. DCM was removed from the reaction by rotary evaporation. Next‚ tert-butylamine (5.0 mL‚ 47.6 mmol) and 5.0 mL of N-methylpyrrolidinone

Evaluate the evidence that visual perception involves bottom-up and top-down processing. The perceptual system is comprised of a of a diverse range of senses including visual‚ auditory‚ olfactory and tactition; the perceptual system is part of the nervous system‚ which contains millions of nerve cells called receptors that sense and respond to a plethora of sensory stimuli including light‚ sound and temperature. The act of perceiving rather than merely sensing enables us to analyse and make sense

Electric eel produce Electricity? A Knifefish also known as an Electric eel is the only species in its genus which can produce electricity. The Electricity is produced within his organs three in specific (Hunters Organ‚ Sachs organ‚ and the main organ). The three organs that generate the electricity within the eel takes up 4/5 of his body‚ which can be a good amount since a common Electric eel can be as big as 6’7. The Sachs organ one of the three organs that produce electricity is associated with
