hey thanks for the vid, excellent stuff. just a quick question. the vid said the diff in EN between Al and H is higher than for B and H, making it's Hydrogen more partially negative (at about 18:00 min in the video). I looked at a ptable and saw Boron has an EN of 2 while Al has an EN of 1.61, so Im a bit confused. Should I just ignore the ptable in this specific case?

[@ChadsPrep]

It wasn't the absolute value of the electronegativity we were looking at, but the difference in electronegativity. For 2 atoms bonded together, the larger the difference in electronegativity, the more polar the bond. Hydrogen has a value of 2.1 (2.2 in some sources). Using your values that would result in an electronegativity difference of 0.1 for the B-H bond and ~0.5 for the Al-H bond. The bigger difference in electronegativity between Al and H indicates a more polar bond (or we could say more ionic character) which is ultimately what I used in the video to explain why it was more reactive. Hope this helps!

ohhhh I gotcha. yep that nails it, I was thinking just magnitudes. great stuff, great vids, I've been going through all of them the past 2 weeks and liking them all. have a great night :D

06:52 Is there a way to selectively reduce just the ketone, but not the aldehyde, or vice versa?

[@siddharthpatel4064]

At the 4:40 mark, you went over the OsO4 in review of the alcohol synthesis reactions. You also used NaHSO3. Instead of using NaHSO3, would it also be possible to use H2O2?

[@ChadsPrep]

Absolutely Siddharth! You'll commonly see NaHSO3, Na2SO3, or H2O2 all used after OsO4 in the second step of syn-dihydroxylation.

Chad, I bet you thought you saw the last of me. I made it to ochem 2

[@ChadsPrep]

Ha! All the best!

[@tilawatkhan9173]

Please reduce your speed of teaching and add some more informations about the catalysts and their names.

[@kiulogakenia]

Watching this in 2024 December ❤
