The single covalent bond is referred to as a sigma bond, denoted by the symbol σ.
The sigma bonds are usually mentioned in valence bond theory to visualize the bond formation between atoms to form polyatomic molecules like H2, CH4, etc., by overlapping their atomic orbitals.
Learning Objective: To study what Van Der Waal forces are in chemistry and their example.
Skill Level - Intermediate
Prerequisites:
The different spatial arrangements organic molecules adopt due to the rotation of the single bond are called conformations. A specific conformation is called a conformer or conformational isomer.
Many such conformational isomers are undoubtedly interconvertible by single bond rotations. So, these isomers are simply different rotational (or structural) arrangements of the same molecule.
Learning Objective: To study how to determine by qualitative analysis the physical properties of the state, nature, odor, color, solubility, and physical constants of an unknown organic compound.
Skill Level - Intermediate
Prerequisites:
Learning Objective: To learn about positional isomerism, a subtype of structural isomerism.

Prerequisites:
Ethanal is a two-carbon aldehyde, and propanone is a three-carbon ketone. The increase in one Carbon number is possible using a Grignard reagent (Methyl Magnesium Bromide, CH3MgBr) to form a new Carbon-Carbon bond.
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.
The unit used to describe the mass of an atom is the unified atomic mass unit, symbolized as amu or μ.
The standard used for measuring the mass of an atom is a 12C atom. Carbon-12 (12C) is an isotope of Carbon with 6 protons, 6 neutrons, and 6 electrons.
The unified atomic mass unit is defined as exactly 1/12 th the mass of one Carbon-12 atom.
The ylide is an electrically neutral molecule that has a negative carbon with an unshared electron pair (usually a carbanion) adjacent to a positive heteroatom (typically nitrogen, phosphorus, or sulfur), where both the atoms have full octets (eight electrons in their valence shell).
The bond between the carbanion and positive heteroatom is best described as a polar covalent bond with significant ionic and double-bond character, depending on the ylide type.
