- The properties of alkanes, and the specific trends you can observe as the length of carbon chain increases
- The equation for the combustion of alkanes
- How to write balanced equations for the combustion of alkanes, with two worked examples

Monkeys (methane) Eat (ethane) Peanut (propane) Butter (butane) Hope this helps x
I wish this man was my teacher because he explains stuff that I couldn't understand at school after 5 lessons on it!

dude, you're actually the best. explained organic chemistry in less than an hour, when my teacher's been trying for months. also, everyone's got (arguably better) mnemonics, but for some reason, this helps me a lot: methheads (methane) eat (ethane) pretty (propane) badly (butane). just easier because i try to think about breaking bad, HAH

there is a formula for complete combustion reaction of alkanes: CnH2n+2 + (3n+1)÷2 = nCO2 + (n+1)H2O, where n is the number of carbon this makes it easier if you are unable to balance the eq

great video but you should have included incomplete combustion as well

Thank u!!! It was so useful!! I am actually doing Cambridge GCE O level but it is actually the same as GCSE!!! Thank u so much for ur lecture, my teachers took 3 weeks to explain Organic Chemistry but you taught everything within few hours and they are pretty detailed, I am just so impressed 😱😱 And you are a better science teacher than my school teachers, they arent experienced and they dont give lectures in English. I am a foriegner and it is really hard for me to understand their lectures as well. I have CAIEs after 6 months. Thank u so much!!!✨
Thank you!

Incomplete combustion is where there isnt enough oxygen in the air so the prooducts would be carbon monoxide + water or + carbon dioxide i think

incomplete combustion is when there's not enough oxgyen in the air so the products would be carbon monoxide + water. and it means that the alkenes reacts with alkenes
