Thank you so much. I've always found your videos most helpful!
AHHH, this is perfect! Thank you!!
Can I use water for the (almost) non polar carbon ring that contains ester? What if I use LAH and THF for solvent and HCL at the last time?
Why doesn't NaBH4 reduce carboxylic acids, acyl chlorides nd esters??
Why didn't the water react after the LiAlH reacted the first time but the LiAlH again had to react twice before water reacted later...
The first time the oxygen broke a O-C bond (by forming the pi bond) which is weaker than the C-C bond it would have broken the second time around.
My textbook uses H30+ ion for protonation. I understand the protonation through H20 but can anyone explain the mechanism through H30 ion?
It has an active H+ ion which makes protonation and oxidation faster. There is no big difference between them
at 9:22 why doesnt lialh4 reduce the alkene near benzene
+Rahul Singh NaBH4 and LiAlH4 dosent reduce alkenes, it reduces alkohols. To reduce alkenes you can use halgoenireduction or hydrogen as showed.
oh dearie me :D
So why did the LiAlH react twice?
Sheel Patel Because it turned the ester --> aldehyde --> alcohol.
+Sheel Patel Because it was in excess. It will react first to form a ketone, then second to form the alcohol.
@@sarahong4589 really... So whenever you're reducing an Ester.. Does It have to first become an aldehyde first before an alcohol??
