Reactions of Alkenes

This content will be covered over the rest of the week, so this post will be updated regularly.

Here is an introduction to two of the most simple reactions of alkenes: combustion and addition:



The first task we started with today was to draw and name as many isomers of C6H12 as possible...this was tough!! According to the internet, there are over 20!!

Then, we were taught about oxidation and polymerisation:

Alkenes - Introduction

Alkenes are unsaturated hydrocarbons. The functional group is a C=C bond (double bond). This lesson was based around the isomers and nomenclature of alkenes:



Here is the activity we started with that shows alkenes have the same general formula as cyclic alkanes:

Here is the activity we did at the start on Monday's lesson...just a little tougher:

Reactions of Alkanes

We were shown a couple of simple reactions of alkanes: combustion and substitution.



Then we had to do balanced equations for these and learn about "cracking":

Alkanes - Introduction to Organic Chemistry

I'm not a fan of teaching this topic the way Beginning Chemistry does. I prefer to "get into it" with the functional groups and cover types of reactions, nomenclature and isomerism over and over again, in context. So, we jumped straight into using MolyMods to make as many isomers of C5H12 as possible.




Here are the questions we tried at the start of the next lesson:
