7:58 why in this reaction do we use methanol unlike the first reactions when we used H+? like how did you know to just use methanol

[@sindhu...18]

I think,to reduce ketones alcohol should be used as a solvent

[@shiveshkumar890]

sir in da abv rxn 'H' [BH4] has positive charge ,hw can it attach to the carbo cation .please clear my doubt,sir

[@cartoonjoystick]

Is this a SN2 mechanism? I need fast answer :)

[@mistersirisaacnewton]

+Cartoonjoystick nah it's not SN2. If it was SN2 that would indicate that the BH4 would stay bonded and the oxygen would leave (which wouldn't happen since SN2 reactions normally have halides as leaving groups)

[@equfrj2296]

Is this mechanism a consequence of the oxymercuration of an alkene?

[@alesgrundzi791]

anyone stuck confused on how to do the LiAlH4 + Aldehyde? :(

Simply too fast....much better videos with good pacing and far more
sophisticated diagrams available on UA-cam..............
