what if at the end we washup using a Base instead of an acid. My textbook uses a base but doesn't show the actual mechanism. just the final product which is the same as a washup with an acid.

Hey i have a question! Hiw does Alh2 combined with O makes it a good leaving group rather then simple O?

@Leah4sci

2 ай бұрын

If you're referring to the negatively charged oxygen leaving the structure at 7:40 in the video, having that oxygen leave would make the central carbon unstable as it would become a carbocation with less than an octet of electrons. The AlH2-O is a good leaving group because the oxygen is highly electronegative and is capable of holding that negative charge when apart in solution. Aluminum alone would not be happy leaving as a hydride either, as I explained in the video around this time. For further questions, make sure to reach out to me through my website at Leah4sci.com/contact

A video from Khan academy says that the reduction of carboxylic acids and esters follow the same mechanism unlike what you said ...Also the balanced equation in our textbook has no mention of hydrogen as a by product . There is only a water molecule. Can anyone help with it ?

The goal of this video is to teach you the concept. If your resources don't match up focus on understanding why each step is as it is. This way you'll know which is correct regardless of what the resources tell you. Especially with biproducts not mentioned

At 7:06 why there is no positive charge on Alh3

@Leah4sci

3 жыл бұрын

The formal charge on aluminum in AlH3 is zero. Notice that AlH4 carried a negative charge. When its hydride left and attacked the acidic hydrogen, it then lost that negative charge and became neutral.
