Atomic Radius: Covalent vs Van der Waals Radius

How big is a carbon atom, 76 pm or 170 pm? A 5-minute audio lesson with slides on how chemists measure atoms with no edge. We cover covalent, van der Waals, ionic and metallic radius.Slides, transcript and the tutorials this episode is based onSubscribe to Introductory Organic Chemistry

Why neutral molecules like water can act as powerful nucleophiles in organic chemistry mechanisms. In this explainer, we break down what makes a nucleophile work and why a negative charge isn't required for a molecule to donate electrons. This episode walks through the exact mechanics behind how neutral molecules attack electrophiles.Slides, transcript and the tutorials this episode is based onSubscribe to Introductory Organic Chemistry

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.Reference Article This excerpt is part of the chapter Intermolecular Forces, part of the Organic Chemistry Fundamentals study program. Study Program on Organic Chemistry FundamentalsCurlyArrows has created a beginner's guide - Organic Chemistry Fundamentals covering 14 fundamental chapters required to master organic chemistry reactions.

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. This excerpt is part of the chapter Bonding in Atoms, part of the Organic Chemistry Fundamentals study program. Original Article Study Program on Organic Chemistry FundamentalsCurlyArrows has created a beginner's guide - Organic Chemistry Fundamentals covering 14 fundamental chapters required to master organic chemistry reactions.

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.Here is the link to the article  Study Program on Organic Chemistry FundamentalsCurlyArrows has created a beginner's guide - Organic Chemistry Fundamentals covering 14 fundamental chapters required to master organic chemistry reactions.

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.Subscribe to Introductory Organic ChemistryTake the Quiz!
