Explore the mechanism of nucleophilic substitution on alkyl halides, highlighting backside attack and the role of steric hindrance in primary, secondary, and tertiary cases.
Delve into acetylation and substitution reactions, detailing how a hydrogen on a ring is replaced by a group under anhydrous conditions with Lewis acids. Explore the mechanism and byproduct formation.
Ammonolysis of alkyl halides proceeds by ammonia's lone pair attacking the alkyl carbon, yielding primary, secondary, or tertiary amines; excess ammonia can drive over-alkylation unless stoichiometry and solvent are controlled.
Explore the esterification mechanism between carboxylic acids and alcohols, showing water elimination, concentrated acid catalysis, and the reversible nature of ester formation. Understand how isotopic labeling demonstrates the origin of water and how dehydration drives the reaction, with relevance to exams and MCQs.
In mcq 9, learn electrophilic aromatic substitution on benzene, showing how activating and deactivating groups like bromine alter electron density and direct attack.
Explore base-induced removal of alpha hydrogens, formation of carbanions, and the resulting attack on carbon, highlighting major reaction pathways under different base strengths.
Explore the order of reactivity among three reactants in a hydrolysis mechanism, highlighting how lone-pair conjugation, hybridization, and resonance stabilize intermediates and shape reaction pathways.
Compare carbon–halogen bond strengths, reveal that carbon-iodine bonds break more readily than carbon-chlorine bonds, and explain how resonance stabilizes carbocation intermediates, guiding silver nitrate precipitation tests.
Explore the reaction of concentrated sulfuric acid with acetic acid, identifying the main products and ionization behavior. The discussion covers proton transfer, resonance, and concentration effects on acid-base outcomes.
About Course - 2: ( Organic Chemistry basics for 12th Standard, NEET, JEE and MHTCET,MCQ) {+10Hours}
[9 Free Preview Lectures]
This Course - 2 is designed to help students, understand organic chemistry and remove the fear of organic chemistry.
My experience says that, students feel organic chemistry is difficult because they do not follow the proper sequence while studying organic chemistry. ( Please enjoy 9 PREVIEW lectures before joining).
Proper Sequence : 1) INTRODUCTION
2) Concept of HYBRIDIZATION (11th Level) (Course 1)
3)Effects in Organic Chemistry (Inductive effect, Electromeric effect, Resonance, Hyperconjugation etc)
(11th Level).(Course 1)
4) Reactions & Mechanisms.( 12th level) (Course 2)
5) Advanced MCQ discussion.( 12th level).(Course 2)
Without having conceptual hold on Hybridisation, one cannot get conceptual control of various effects like Inductive effect, Electromeric effect, Resonance, Hyperconjugation in Organic Chemistry.
Without Knowledge of these effects we cannot study chemical reactions in Organic chemistry and their mechanisms. So skipping these steps it will be impossible for a students to solve multiple choice questions (MCQ).
In Course - 1, after explaining the concept of Hybridisation, I have explained various effects in Organic chemistry. After this part-I have shifted my lectures to organic reactions and their mechanisms.
The selection of organic reactions and their mechanisms in this Course - 2 is done randomly without considering the sequence of topics in the textbooks.
This I have done deliberately because once you are done with concept of Hybridisation and effects in Organic Chemistry, you become capable of studying chemical reactions and their mechanisms in Organic chemistry, irrespective of their sequence in the text book.
Finally I have discussed few advanced level MCQs. If students follow the above sequence through my Course - 2 then it will help them to develop the confidence and will make them capable of successfully facing various exams like NEET, JEE and MHTCET.
