    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

    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!!!✨

      @selfstudy7358 4 года назад +6

      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
