Organic Chemistry Question and Answer: Basic Concept: Organic Reaction Intermediates Q. What are carbocations and what are their types? Ans: Organic cationic species having +ve charge on an sp2 hybridised carbon atom is called a carbocation. This positive charge on carbon may further be delocalised due to shifting of electrons by resonance involving an unshared pair of electrons or a double or triple bond at allylic position. These are called the classical carbocations . Examples include: CH 2 = CH – CH + , PhCH 2 + , R 2 CH + These are formed by heterolytic cleavage of a C -X bond or by protonation of alcohols or by protonation of alkenes. But in a nonclassical carbocation, the positive charge on c...
