WebA carbocation, also sometimes referred to as the carbonium ion, is an sp2 hybridized carbon atom with three groups bonded to it and a empty orbital. Because it has an empty orbital, the sp2 carbon carries a positive charge on it, making it highly electrophilic (want to know more about electrophiles ? Check out this blog post). WebIn this experiment, cyclohexanol is synthesized from cyclohexane and phosphoric acid. There are three steps to this reaction mechanism. First, the protonation of oxygen occurs, and a leaving group is formed. Then, the leaving group leaves, and a carbocation is formed. This step is the rate determining step for the reaction. Lastly, there is the ...
