The Friedel Crafts Acylation Of Benzene

In this video I explain the Friedel Crafts acylation of benzene reaction mechanism in detail. I explain the difference between a nucleophile and an electrophile and how electrophiles are generated using an acid chloride and acid anhydride. I also explain the concept of ortho, para and meta directors and how you can predict the major and minor products of a reaction.

How To Solve Friedel Crafts Acylation Of Benzene Synthesis Problems

In this video I explain how to complete synthesis questions using benzene and mono-substituted benzene questions. I walk you through each type of question and show you how to link the reagents and conditions to each step of the question to take you from the starting compound to the final compound.

Writing And Balancing Complex Half-Reactions In Basic Solution

In this video, I show you how to balance them in basic solution. And. I also show you how to balance a half equation with fractional oxidation states.And, I also show you how to balance a half equation with fractional oxidation states.

Balancing Redox Reactions In Acidic Solutions Practice Problems Explained

In this video, I complete past paper questions on the disproportionation of chlorine in water, the reaction of a metal sulfide with nitric acid and the extraction of titanium from titanium ore. When solving these problems I also review how to determine the variable oxidation state of an atom in a compound and balance half equations in acidic media. 

Bronsted Lowry Acids And Bases In A Level Chemistry Made Easy

In this video, I explain the difference between Arhennius definition of acids and bases and the Bronsted Lowry definition of acids and bases. I teach the concept of proton transfer and conjugate acids and bases. I explain the difference between strong acids and bases and weak acids and bases and list the common acids and bases you will see on the A-level exam. I explain the autoionisation of water and how it is temperature dependent. And I use the Kw of water to derive the pH equation.

pH Calculations For Strong Acids And Bases Made Easy

In this video, I explain how to calculate the pH of a solution of a strong acid and a strong alkali. I also explain how the pH of a solution depends on its temperature how to write the ion product of water. Finally, I explain how to calculate the ph of a solution where acid has been neutralised by a base.

pH Calculations For Strong Acids And Bases Made Easy 

In this video, I complete the PPQ started in the last lesson and explain how to write the ion product of water and use it to calculate the pH of a strong acid and base mixture. And I also discuss the dependency of Kw on temperature and why the pH of a solution changes with temperature. I also discuss the nature of weak acids and bases and explain how to write the Ka expression for a weak acid. And I show you how to calculate the pH of a solution when a weak acid has been neutralised by a strong base.

Chemical Equilibria In A-Level Chemistry Explained

In this video, I explain the concept of chemical equilibria and the difference between homogeneous and heterogeneous equilibria. I also explain Le Chatelier's Principle and the effect that changing the concentration and the pressure of the reactants or the products has on the equilibrium position. And, I also explain the effect that changing the temperature has on the equilibrium position and how it changes the magnitude of the equilibrium constant Kc.
