In this CurlyArrows 'Learn Chemistry with Sibi' Podcast, I covers the four common mistakes a beginner in chemistry makes while drawing a Hydrogen bond.
1) Number One – Choosing the Wrong Atoms
2) Number Two – Choosing the Wrong Donors and Acceptors
3) Number Three - Not Maintaining the Hydrogen Bond Angle
4) Number Four - Place incorrectly the Dipoles

In this 2-minute podcast on Hydrogen Bonding on CurlyArrows 'Learning Chemistry with Sibi', we will learn how this weak-but-mighty force works, and why it only happens with H attached to O, N, or F. Hydrogen bonding is why water is a liquid, and our DNA stays twisted in that perfect double helix.

In this podcast, we will look at how the distribution of two electrons between two atoms in a covalent bond gives rise to a bond type based on polarity, creating two variants: polar and nonpolar covalent bonds. These covalent bond types are essential in organic chemistry, as they are responsible for various molecular interactions, solubility, and transformations.

In this audio, we will cover the basic vocabulary related to acids, Lewis, Bronsted-Lowry, and Arrhenius. We will also see how the strength of an acid is measured using Ka values, and try to understand what a conjugate acid-base pair is. We will also discuss polarizability and the hard-soft acid-base concept.

The world of the atoms can seem strange and counterintuitive, governed by probability. Still, we can't help but see parallels when we try to grasp their world through the lens of our own. In the language of chemistry, lone pairs are an atom's valence shell electrons that took part in hybridization but evaded the covalent bond formation with other atoms.

Lone pair is covered in detail in the chapter Fundamentals of Organic Reactions where we discuss various bond formation theories and other covalent bond properties.

Common names were the earliest attempts to identify compounds, which were later followed by a systematic, rule-based IUPAC nomenclature system. Prefixes like n-, iso-, neo-, sec-, and tert- are part of those retained common names that are sometimes used to identify and distinguish between branched and unbranched structures.

Single bonds have an absolute privilege and exclusivity to show bond rotations, a prime reason behind various conformations in organic chemistry. Conformations are various interconvertible arrangements, or shapes molecules adopt due to their flexibility to undergo bond rotations. The molecules' identity remain the same throughout these rotations.

Conformational isomers are covered extensively under the branch of stereochemistry that considers molecular shapes and studies their reactions.

Around the 1780s, chemists began classifying compounds based on their source. In those days, any compound obtained directly or indirectly from living things like plants or animals was called an organic compound. With the downfall of the Vital Force Theory, the term organic underwent changes. Listen to what changes occurred after 1780, which put the spotlight entirely on a few elements from the periodic table that are still constantly changing our lives and organic chemistry.

Functional groups provide a mechanism to enable molecular transformations like - connecting two molecules, rearranging a group of atoms in a molecule, replacing one group of atoms with the other, or even removing unwanted atoms. In organic chemistry, these changes occur in the form of reactions- addition (connect), rearrangement (rearrange), substitution (replace), and elimination (remove).

Two molecules having the same molecular formula may be believed to look alike and related, but they aren't. The expanded structures of these molecules will reveal the truth - they differ in how the atoms are connected, making them structural isomers of each other. These variations are classified into six subtypes (chain, position, functional, tautomerism, metamerism, and ring-chain) and are covered in detail in the chapter 'Structural Isomerism' on curlyarrows.com.

Representations have existed since the dawn of human civilization. In chemistry, we often use shortened and elaborate representations, using wedges, dots, rings, and chains. These symbols form the new language of chemistry and are covered in detail in the chapter 'Drawing Organic Structures' on curlyarrows.com.

Knowledge of common reaction types in organic chemistry will help identify, predict, and design reactions. CurlyArrows has categorized common molecular transformations into six reaction subtypes- addition, elimination, substitution, rearrangement, oxidation-reduction, and decomposition. It also briefly covers the three main mechanisms by which such changes occur.

The chapter on the atom, part of the introductory organic chemistry course, briefly covers the study of an atom and its constituents, mainly the electrons. Several chapters discuss their position and occupancy in various atomic levels -s, p, d, and f. An atom's electrons are taught to rearrange into two sets- reactive valence electrons and inert core electrons along with the steps to determine them using group and atomic number.
