If you are having trouble with the Reduction Mechanism of NaBH4 (Sodium ...

If you are having trouble with the Reduction Mechanism of NaBH4 (Sodium Borohydride) or LiAlH4 (Lithium Aluminium Hydride) this is the perfect video lesson for you! (Note there is a little correction, please check below for it. My LiAlH4 Mechanism for the reduction of the carboxylic acid needs to be edited. Sorry!)

Got a final or MCATs coming up? Test your skills when it comes to reducing agents in this video!

Sorry about being a little M.I.A. lately but you guys get an extra long video in compensation :]. It's actually my longest video thus far. I'm usually a bit OCD about long videos but I made sure I packed in some fun and change in scenery here and there to keep you guys awake. Also part of the reason why it's so long is that I combined the "bloopers and outtakes" with this video and they are in the end for any one not taking Orgo anymore and just want to see some fun parts. :]

●LiAlH4 Reaction Map: http://upload.wikimedia.org/wikipedia...
●Correction!
Special thanks to Bhaveya Saraogi who pointed it out to me. But my LiAlH4 Reduction Mechanism for the Carboxylic Acid needs to be tweaked a little. I double checked some resources and I must have gotten the mechanism for LiAlH4 reduction of esters and carboxylic acids mixed up. So everything is correct in this video except for the the first and second step of my LiAlH4 Reduction of the Carboxylic Acid. And the mechanism I show for the Carboxylic Acid would apply if you were reducing an Ester down to an alcohol. Sorry again for any confusion!

The correct mechanism is here if you'd like to check: http://chemwiki.ucdavis.edu/Organic_C....

أهمية العلوم الشرعية| علوم الكتاب والسنة| ثمرة علم دراسة الأسانيد هو تمييز الصحيح من الضعيف مما أضيف إلى الرسول صلى الله عليه وسلم| وهذا المقرر شرح وتغصيل لما سبقه من دراسة مصطلح الحديث الشريف| ومن نتعرف على الجهود المضنية التي بذلها الحفاظ والنقاد في خدمة هذا العلم المنيف.

والإسناد من خصوصيات هذه الأمة| ولا يصل إليه الراغب فيه إلا بطول المدارسة والمراجعة| وادمان النظر في أصول هذا العلم وموارده.
