Electronegativity
Electronegativity measures on a scale of 0.8 – 4 an atom’s or group of atoms’ tendency to attract the bond electron pair towards itself, thereby creating partial negative (δ-) and positive (δ+) terminals.
Organic Chemistry
How does molecular geometry or shape influence reactivity?
The arrangement of groups around a central atom creates its three-dimensional shape. And this shape affects how it interacts with other molecules or ions.
The interactions could be bonding - to form new bonds or nonbonding- affecting the physical properties of solubility, melting point, boiling point, polarity, and more.

Skill Level - Intermediate
Prerequisites:
Activation Energy (Ea)
The activation energy (Ea) is the minimum amount of extra energy absorbed by the reactant molecules from an energy source such as heat, light, etc., to attain the threshold value for effective collisions to occur and thereby to form an intermediate complex (active state) that finally results in product formation.

Atom
Atoms are the starting point for studying organic chemistry. In our Chapter, we start by introducing the structure and components of an atom, covering protons, neutrons, and electrons.
