Explore acid and base reactions through Lohri theory and Lewis theory, defining acids as proton donors and bases as proton acceptors, noting conjugate base and conjugate acid relations.
Learn how resonance, induction, and orbital effects, together with electronegativity, govern acidity by stabilizing conjugate bases and charge distribution, with sulfur vs oxygen and nitrogen vs oxygen examples.
Explore resonance as a stabilizing factor for charge, compare acidities among carboxylic acids, alcohols, and phenols, and see how delocalized conjugate bases increase acidity.
Explain induction as a through-bond electronic influence: electron-withdrawing halogens increase acidity by stabilizing the conjugate base, while alkyl groups donate electrons and decrease acidity; note steric hindrance on nitrogen.
Explore how hybridization affects acidity and stability in organic molecules, comparing sp, sp2, and sp3 carbon behavior, electronegativity, and notable exceptions.
Examine how acidity and basicity vary with substituent effects near a carboxylic acid, illustrating chlorine proximity and electronegativity as drivers of proton removal and hydrogen leaving.
Examine how the rate of reaction depends on both chloride and hydroxide concentrations in second-order kinetics. Contrast this with first-order steps in a two-step mechanism.
Examine sn1 and sn2 substitution reactions, comparing mechanisms, substrate and nucleophile effects on rate, inversion in sn2, and the role of carbocation formation in sn1.
Analyze leaving group identity and conjugate base stability to determine SN1 versus SN2 pathways, noting first-order behavior with stable leaving groups and the exception of a small, charged leaving group.
Identify nucleophiles by lone pairs or negative charge, with examples like nitrogen, phosphorus, sulfur, and anions; electrophiles are electron-deficient targets that drive inversion of configuration in suitable substrates.
Explore how solvent factors, including polar solvents, product solvent, and protic solvents, influence reaction rates by showing how solvent shells around the nucleophile affect its attack on the substrate.
Assess reaction mechanism by weighing nucleophile strength, substrate type (primary, secondary, tertiary), and solvent (polar protic vs polar aprotic) to decide concerted versus stepwise pathways.
Explore substitution reactions by examining the factors—substrate, nucleophile, solvent, and leaving group—and see how secondary versus tertiary substrates, a protic solvent, and a good leaving group steer the mechanism.
Explore elimination mechanisms, E2 and E1, where leaving groups and bases drive alkenes; E2 is concerted and second-order, while E1 proceeds via a two-step pathway with a first-order rate.
Examine the e2 mechanism by analyzing ethanol elimination to yield a major, more substituted alkene (Zaitsev) and a minor, less substituted alkene (Hofmann), with bulky bases and stereochemistry notes.
Explain the two-step e1 mechanism, starting with leaving group departure, then bond formation; protonate hydroxyl to water to create a good leaving group and discuss Zaitsev and Hofmann trans products.
Explore how nucleophiles and bases drive substitution versus elimination in organic reactions, analyzing primary, secondary, and tertiary substrates and SN1, SN2, E1, and E2 mechanisms.
An animated review of substitution and major product outcomes in organic chemistry, analyzing primary versus tertiary substrates with strong nucleophiles or bases and predicting Zaitsev or Hofmann products.
Explore the mechanism of additional actions on compounds with pi bonds, distinguishing symmetrical and asymmetric alkenes, and using CIP priority to assign cis/trans (Z/E) configurations.
Explore Markovnikov and anti-Markovnikov rules for adding hydrogen halides to alkenes, identifying hydrogen addition to the hydrogen-rich carbon. Observe peroxide-induced anti-Markovnikov orientation, unlike reactions without peroxides.
explains acid-catalyzed hydration to form primary or secondary alcohols, outlines an oxidation step, and introduces oxymercuration-demercuration as a key addition method in organic chemistry.
This lecture reviews the MacNicol rule and peroxide effects, and explains acid-catalyzed hydration of alkenes with sulfuric acid to form primary, secondary, or tertiary alcohols.

Hi, hope you're doing well.
Welcome to our world of the organic chemistry, the place that encourages you to learn and love learning and removing all the obstacles that makes you struggle with organic chemistry.
My name is Ahmad Hegazy. I am very passionate about organic and biochemistry. My purpose from this course is to serve you by removing all the barriers that could make you don't get good grades at organic chemistry.
I'm here to help you to change your perspective about that organic chemistry so hard to understand.
Within our journey we will encounter some topics like Substitution, elimination and additional reactions.
We will also understand in depth acidity and basicity, resonance and inductive effect.
Before I made this course. I asked my friends what was the most hard topics that they suffered from understanding.
That's why I made this course for you so you won't struggle anymore
Also I made this course carefully and it was reviewed by the best professors
And I promise you after this course you will find organic chemistry so easy to study whether from YouTube or from the textbooks. If you didn't understand anything of the course you're totally free to ask for a refund.
This course is made for college students who want to understand the basics of organic chemistry reactions.
Some reactions need imagination so you can understand them well. We've put something like this into consideration and did my best to make all the animations easy, simple, and clear.
I made after each section some exercise to solve it together to make sure you understood everything I said.
I hope you'll like this course and stay tuned for more courses.
