Hi, I am a bit confused about the soap part. You circled the O- group as hydrophillic but everywhere i've looked it says that the COO- group is hydrophillic and the rest of the hydrocarbon chain is hydrophobic
Agreed - glad it’s not just me that sees the glycerol looses the OH not just the H. Also the ester can’t lose the O the ion can’t exist in that form. To be fair this error is all over the internet even in the CGP A level revision book. Have to search far and wide to find it correct. I trust Chemguide.
Thank you so much for these videos! They have been super helpful :)
You're very welcome!
Do we have to learn the whole soap structure?
thank youuuuu so much!!!!! the videos are actually helpful...
Glad you like them!
Great Video

Yes I think it’s an error too. I forgive him though cause his other videos are brilliant.
Shouldnt the Oxygen in the ester be part of the carboxylic acid? I see u made it a part of the triglyceride in the drawing
