Chemical Bonding and Molecular Structure

Types of Chemical Bonds

Chemical bonding is the attraction between atoms. The bond between two atoms is what causes a molecule to be a substance. The bond between atoms also gives a substance its chemical properties. The strength of a material and its ability to resist breaking is determined by its chemical bonds. These bonds hold the molecules of […]

Triple Bond

A triple bond is a chemical relationship between two atoms that has six bonding electrons rather than the two seen in a covalent single bond. Because triple bonds have a bond order of three, they are stronger than single or double bonds. The most common triple bond in alkynes is one between two carbon atoms.

Trigonal Bipyramidal Shape of Molecules

A trigonal bipyramidal molecule is a little more difficult because there are more atoms and bonds to consider. A trigonal bipyramidal form resembles two three-sided pyramids sharing a side, as the name suggests. It has a steric number of 5 because it has a core atom with five bonds. The trigonal bipyramidal is made of

The Triangular Shape of Molecules in Chemistry

Introduction The five main shapes of molecules according to the VSEPR theory are linear (example: CO2), Trigonal Planar (example: BCl3 ), Tetrahedral (example: CH4), Trigonal bipyramidal (example: PCl5 ), and Octahedral (example: SF6). A few questions arise. Are there molecules in ‘triangular shapes’ with atoms/molecules as vertices and bonds as the sides of the triangular

Tetravalency of Carbon

The capability of carbon to establish bonds with other atoms by participating its valence electrons is known as tetravalency. This principally means that carbon has four valence electrons ( external electrons that are available for forming bonds with other titles), carbon is called tetravalent. A tetravalent element is an essential with four electrons available to

Symmetric Hydrogen Bond

When a hydrogen atom attracts an electronegative atom via dipole-dipole attraction, hydrogen bonds form. Hydrogen bonds are most commonly formed between hydrogen and fluorine, oxygen, or nitrogen. Intramolecular bonding, or bonding between atoms within a molecule, is more common than bonding between atoms of different molecules (intermolecular). Intramolecular Hydrogen Bonding An intramolecular hydrogen bond occurs

Sulphur Trioxide

Sulphur trioxide, or SO₃, is a chemical compound with the chemical formula SO₃. Sulphur trioxide comes in a variety of forms, each with its own molecular species and crystalline structure. It is colourless in liquid form and emits fumes in ambient settings. It is a highly reactive chemical that is also a strong oxidizer and

Strength of the Hydrogen Bond

Hydrogen bond was a controversial topic in the early 20th century. However, during the mid-20th century, the concept of weak conventional hydrogen bonds was understood and accepted by masses as it evolved from the term hydrogen. Unlike the covalent bond, whose strength varies within the factor of ∼4 (30–120 kcal mol−1), the hydrogen bond is

Stereoisomerism

Isomerism is the phenomenon in which the molecules have the same chemical formula but different structures. It can be further classified into two categories: Structural Isomerism: The molecules with the same chemical formula but different attachments of the atoms with the central metal are called structural isomers, and the phenomenon is called structural isomerism. Stereoisomerism:

Stability of Conformations

In a sigma molecular orbital, the distribution of the electrons is balanced around the internuclear axis of the carbon-carbon (C-C) bond. Hence, it allows free rotation around the C-C single bond. The three-dimensional arrangements of carbon atoms in space are observed due to this rotation, and these atoms can be changed into one another. Such
