Classification of Drugs- Chemistry in Everyday Life
Drugs are small molecular weight compounds (<500) that in moderate doses show a therapeutic (beneficial) effect and in high doses show harmful effects. They interact with the macromolecular targets (carbohydrates, proteins, fats and nucleic acid) to produce a biological response.
Differentiating complete structural formulas and condensed structural formulas using examples
Draw complete structural formulas and condensed structural formulas for
a) three compounds of formula C3H8O
b) five compounds of formula C3H6O
The condensed structural formula disguises the molecule's true vastness by revealing only the number of atoms present. What remains hidden from sight are the bond connections, the bond angles, and their three-dimensional arrangements, so what we observe is just the molecule's literal condensed form.
How to identify a functional group from an IUPAC nomenclature- with three examples
The longest carbon chain is the parent chain containing the principal functional group.
The principle functional group is always given the highest priority, lowest number (1 before 2, 3, 4...), and assigned as a suffix while writing the nomenclature. Therefore, the numbering of the parent chain always starts from the principal functional group.
Effective Collisions
Effective collisions result in product formation due to an increase in the rate of a chemical reaction. It occurs when the two reactant molecules are correctly oriented and have attained the threshold value (or the activation energy value) at the time of the collision.
Molecular models for organic structure representation
Molecular models are tools used for classroom or research to visualize better and interpret three-dimensional structures of organic molecules. The toolkit can be made of wood, plastic, metal, or other materials.
These models are digitally represented using computer graphics covered under molecular modelling, a branch of chemistry that uses computational and theoretical methods to model and mimic the molecule's behaviour in chemical and biological environments.

The Electron - An atom's reactive component
Learning Objective: To learn about the nature of the electron, an atom's reactive component. The article also helps to understand why the elctrons behave differently as a sub-atomic particle with its dual wave-particle behaviour, ushering in a new field of quantum mechanics.
