Addition to Carbon–Carbon Multiple Bonds

Introduction There are four types of reactions in  organic chemistry----------1. Addition reaction                                                                                                      2. Elimination reaction                                                                                                     3. Substitution reaction                                                                                                     4. Rearrangement reaction Let us know more about the Addition reactions, particularly addition to carbon-carbon multiple bonds. Basically addition to a double or triple bond can takes place in four different ways.                              1.Two-step processes, with initial attack by a nucleophile,                             2. Two-step processes, with initial attack upon an electrophile                             3.Two-step processes, with initial attack upon a free radical. The second step of the reacti
