EXERCISE 1 (Synthesis experiment) Electrophilic Addition

Electrophilic addition Presented to Introduction An electrophilic reaction occurs when a molecule is attacked by an electrophile (Prentice-Hall Media, 1979). Bromination is one of alkene-halide addition reaction, which involves a reaction of an alkene an electron with electron deficient end of the polarized bromine end. This experiment involves addition of

Organic reaction An organic reaction goes through predictable reactions. The chemical reactions has particulars mechanism, such that it is possible to predict the likely product by studying the mechanisms for a specific type of reaction, before using the mechanisms for any initial materials with the correct functional group. The reaction
