Answer to Question #223410 in Organic Chemistry for Aryan Raj

Question

Study of organic reaction intermediates with special reference to formation and stability.

Answer 1

A reaction intermediate or an intermediate is a molecular entity that is formed from the reactants (or preceding intermediates) and reacts further to give the directly observed products of a chemical reaction. ... For example, consider this hypothetical stepwise reaction:

A + B → C + D.

The carbocation bonded to three alkanes (tertiary carbocation) is the most stable, and thus the correct answer. Secondary carbocations will require more energy than tertiary, and primary carbocations will require the most energy.
