What does it mean by reaction mechanism in organic chemistry..?
an organic reaction mechanism merely depicts how the reaction takes place in relation to the movement of electrons. Adding bromine to an alkene has a typical reaction mechanism that it generally follows, but organic chemistry can be tricky and different factors can influence reaction mechanisms. For entry level organic chemistry understanding, each reaction typically has one general mechanism. As you study organic chemistry in more detail, it quickly becomes apparant that there are many variables that go into understanding a reaction’s mechanism and predicted mechanisms often turn out to be wrong. Many mechanisms are determined after seeing what the products are and working backwords.
