Anti addition
As a bromine molecule approaches perpendicular to the negatively charged pi cloud of the carbon-carbon double bond, its bonding electrons are repelled away from the bromine atom nearer the double bond, leaving it with a partial positive charge. As the positively charged bromine penetrates the pi cloud, a negative bromide ion breaks away from it, leaving a cyclic bromonium ion, in which the positive bromine is boned to two carbon atoms. Backside attack on the bromonium ion by a bromide ion results in a trans products. The bromine is added to opposite sides of the carbon-carbon double bond.
Ideal gas law and meteorological balloon, Balloons are still used to deploy sensors that monitor meteorological phenomena and the chemistry of the atmosphere. It is possible to investigate some of the technicalities of ballooning by using the perf..
