Time Of Flight Calculations

In this video I teach the concept of the time of flight mass spectrometer and how to solve time of flight calculations. I show you how to answer any question you may be asked on how the mass spectrometer works using VIADD and how to rearrange the TOF equation and solve the two major types of problems you will encounter in TOF problems.

Back Titrations

In this video I teach the concept of back titrations. I show you how to complete any back titration you may be asked on your exam using a simple diagram. Then I shows you how to complete the two major types of problems you will encounter in back titration problems. One in acidic media and one in alkaline media!

Benzene Structure And Stability

In this video I explain the conjugated pi bond system found in benzene using hybridization theory so that you understand the chemical reactivity of benzene. I explain how to name arenes which are compounds that contain benzene rings. And I also explain when to use benzene and when to use phenyl when naming arenes.

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.
