The outermost electrons of an atom that are mostly involved in bonding reactions are called valence electrons. These electrons are farthest from the nucleus and have high energy.
For example, the total number of electrons in Lithium is three distributed in two energy levels, closest to farthest from the nucleus- 1s2 2s1.
Learning Objective: To learn different methods to stabilize a carbanion.
Skill Level - Advanced
Prerequisites:
1) The first step is find out the Degree of Unsaturation (the number of double bonds or the presence of a ring) in the compound.
The formula is,
Learning Objective: To learn about the different types of orbitals housing electrons in an atom, their visual representation, meaning, and their energy levels.
Skill Level – Intermediate
Prerequisites:
Nucleophiles are electron-rich species that can donate a pair of electrons and form a new covalent bond with an electron-deficient counterpart called the electrophiles. That is why electrophiles are referred to as lovers of electrons.
The nucleophiles donate electrons as lone pairs, pie bonds, or sigma bonds.
Read- What are nucleophiles?
Learning Objective: To study how the presence of a lone pair on the central atom of a molecule contributes to Hydrogen bonding, a type of intermolecular attractive force.
Prerequisites:
Full Charges | Partial Charges | Transient Charges |
|---|---|---|
Atoms attain full charges (+ or -) by losing or gaining electrons and forming ions. So, a full charge on an ion is equivalent to the charge of a proton (in case of electron loss) or an electron (in case of electron gain).

A carbanion is a negatively charged, trivalent carbon ion that acts as a reactive intermediate in many organic reactions.
With three bonds and 8 electrons, carbanions are electron rich and act as a base forming a C-H bond or as a nucleophile forming a C-C bond.
Learning Objective: To learn about the intermolecular forces and how they impact an organic compound's physical properties.

Prerequisites:
Lattice points are the positions an atom, ion, or molecule can occupy in a crystal giving it its shape and characteristics. If any of these particles go missing or are not in a correctly ordered arrangement, it can introduce a defect in the crystal. Lattice points are essentially a crystalline framework.
