this is actually incredible; i’m learning all 3 sciences’ content through your videos and, for once, i genuinely understand topics i used to find difficult! i feel confident now- my gcse exams are next month, i can’t thank you enough.

[@ashleyyy955]

@@Lamplovr tbh, i was really lazy during the year leading to my exams, but binge watching cognito and freesciencelessons a few months before mocks/the final exams really really helped i also found that making a good revision schedule helped loads, if you're motivated enough then it's actually really easy to follow and include good break times :) there was also a channel (ExamQA) who did lives hours before different exams for that specific exam's revision, i'm not sure if they'll be doing it again but there might be other channels if you look good luck with your exams!!!

thanx cognito. its so helpful

I like your explanations

[@harry-ji2pq]

at 1:16 should it be called a reversible reaction arrow? Equilibrium is slightly different. I may be wrong tho :)

[@ahmadsair1584]

i think its because only a reversible reaction has equillibriam

an extra note for that last oxidisation reaction: not only a carboxylic acid is formed but also a water molecule but idk why cognito didnt show it. either way a very useful video

[@arianhobson8755]

nice

[@AlexButcher-uo2yl]

There maybe a typo in the description; 'carbonates' should be replaced with 'alcohols' for how carboxylic acids are made

[@vibhutg1919]

2:42 i dont understand why there are only 8 hydrogen atoms in butanoic acid... arent there supposed to be 9 hydrogen atoms because butanol had 9???

[@narekmelkonyan5017]

I'm not sure either, maybe it was just a mistake. But I think that it's the way the oxidising agent makes it lose some hydrogens.

[@shaguftarizwan941]

The oxidising agent replaces one Hydrogen atom and replaces it with oxygen....as u can see in the reaction...the product has a O2 with a double bond

[@AB-lz5io]

Can someone explain the reaction at 2:40? You have 4 carbons on both sides but you have 8 hydrogens on the acid compared to the 10 on butanol. What happened to the others? I know we added an oxygen due to the oxidising agent but why lose 2 hydrogens?

[@Medlol]

Oxygen is diatomic, which means it has 2 atoms, One of the atoms reacts with the alcohol to form a carboxylic acid. The other atom reacts with the hydrogen to form -OH. The second hydrogen is in the -COO(H) itself

[@manny__8014]

For example in Ethanoic acid, the formula is CH3OOH, why don't you just put the hydrogen on the end with the CH3 in the start and write CH4OO instead?

[@Cognitoedu]

It’s written that way to help show how the atoms are actually linked together. Not something you have to worry about at the moment, but as you learn more about chemistry, it becomes important :)

[@manny__8014]

@@Cognitoedu Alright thanks!

[@antonroy415]

I know Cognito has basically said this already, and I know I'm 2 years late but it's just so that you can see the functional group, and for carboxylic acids, that would be -COOH
