A reaction that results in the formation of a carbocation is most likely to occur from heterolytic bond cleavage.What is a carbocation?A carbocation is a positively charged carbon atom that is associated with two other atoms in a chemical compound. It is a form of a reactive intermediate (i.e., a high-energy, short-lived molecular species) that is formed as an intermediate in many organic reactions.A reaction that results in the formation of a carbocation is most likely to occur from heterolytic bond cleavage. Heterolytic bond cleavage is the cleavage of a bond between two atoms where the electrons in the bond are not equally shared between the atoms, causing one atom to become positively charged and the other negatively charged. Hence, the main answer is option B (Heterolytic bond cleavage).Explanation:A carbocation can be produced in a reaction that involves heterolytic bond cleavage. In heterolytic bond cleavage, one atom retains both electrons from a covalent bond, while the other atom is left with none. This creates an ion of opposite charges, one positively charged atom and one negatively charged atom, and hence, a carbocation is formed.Therefore, the correct answer is option B (Heterolytic bond cleavage).
