When atoms of different types combine to form molecules, it is a heteroatomic molecule. For example, when Carbon (C) and Oxygen (O) atoms combine under an appropriate reaction condition, it can lead to the formation of two types of products (carbon monoxide, CO, and carbon dioxide, CO2) containing two types of atoms.
A heteroatomic molecule can be diatomic (like hydrogen chloride, HCl), triatomic (like water, H2O), or polyatomic (like methane, CH4).

Prerequisites:
A carbocation is a positively charged, trivalent carbon ion that acts as a reactive intermediate in many organic reactions.
With three bonds and only six electrons, carbocations have an incomplete octet and, therefore, electron deficient. It functions as an electron acceptor and an electrophile forming new Carbon-Carbon (C-C) bonds.
Structural isomerism is the variations in structures between two or more molecules having the same molecular formula.

Identification | Benzyne is identified as a triple bond between two adjacent carbon atoms in a benzene ring. Root- Benzyne (like the triple bond of alkyne) |
Carbocations and electrophiles are both electron-deficient species and therefore are electron acceptors. They are attracted to electron-rich centers. However, the electrophile is slightly different from carbocation.
Electrophiles can have a full positive or partial positive charge due to electronegative atoms creating polarity differences, or they can be neutral uncharged species with vacant orbitals.
For example-
Learning Objective: To learn about different ways by which the formation of a carbon-centred free radical occurs.

Prerequisites:
A metal atom is large, so the nucleus cannot attract and hold its outermost electrons. The metal loses those electrons and becomes positively charged kernels. The electrons then flow in the solid structure passing between these positive kernels.
