Substitution and Elimination Reactions

Substitution and Elimination ReactionsSubstitution and Elimination reactions are two different kinds of chemical reactions that form a part of Organic Chemistry. These reactions are often studied together but are quite different from one another. These are both unique in their own right. Here is a detailed look at the Substitution and Elimination reactions.

Substitution Reaction

It is a kind of chemical reaction wherein the replacement of one functional group in a chemical is compound by another. This reaction is also referred to as ‘single replacement reaction’ or ‘single displacement reaction’. This reaction is of utmost significance in organic chemistry. It is divided into two categories: Nucleophilic and Electrophilic.

Periodic Table Trends

Periodic table trendsIn periodic table, elements are categorized based on their electronic structure. This makes the recurring element properties noticeable in this table. Here is a look at the periodic table trends of electronegativity, atomic radius, electron affinity, metallic character and ionization energy.

Periodic Table Trends

  1. Electronegativity

Electronegativity is the ability of an atom to pull electrons towards it. It shows how an atom can swiftly form a chemical bond. Electronegativity usually rises from left to right. It sees a decreasing trend when you move down a group. However, there are exceptions to it at times. Two atoms have a greater chance of forming a chemical bond when the difference between their electronegativity values is larger. The electronegativity of atoms is affected by the distance between the nucleus and the valence electrons and the atomic number.
