Really awesome videos dear 💕sir I am a good student but due to reservation in our country I am unable to get admission in IIT but your videos made me feel like I am studying in IIT. I am really thankful to you. You are doing a noble job for students like me. I have gone through all of your videos and what I have extracted from them is a lot of precious knowledge. I also thanks ambani's jio for internet. Once again thanking you.

Sir can you suggest some book for Advance stereo selective synthesis..?

Thanks sir🙏

Sir what is the relation between diastereoselective and setreoselective reactions

@amitbasak4819

3 жыл бұрын

Stereoselective Reactions are divided into two: enantioselective reaction and diastereoselective reaction. In enantioselective reaction, one enantiomer is formed in preference to the other. The degree of selectivity is measured by the enantiomeric excess. In a diastereoselective reaction, one diastereomer is formed in preference to another. In this case, either two or more stereo enters are formed in a single step such that one relative stereochemistry (e.g. syn or anti) is favoured or a pre-existing stereo enter influences the stereochemical outcome during the creation of another. The degree of relative selectivity is measured by the diastereomeric excess. Example: addition of ethyl magnesium bromide to 2R-2-phenylpropanal to give one major diastereomer (outcome predicted by Cram’s model) or formation of meso-2,3-dibromobutane from Br2 addition to E-2-butene or formation of dl-2,3-dibromobutane from Br2 addition to Z-2-butene etc.

Plz arrange the vedio sequence type so understanding is better

Sir,is Sn1 reaction nonstereoselective and nonstereospecific? Kindly reply.

@amitbasak4819

2 жыл бұрын

Yes, SN1 reactions are non stereospecific as well as non stereoselective, because the nucleophile approach is not governed by the structure of the reactant (non-stereospecific). As the product is usually a racemic mixture (considering the reaction is happening at an existing sp3-stereogenic center (chiral center)). Only in case of tight ion pair mechanism, as the nucleophile mostly approaches from the backside, the reaction is stereoselective as well as stereospecific.

Actually SN1 is characterized by partial racemization where inversion is more than retention thus it would be Stereoselective reaction not specific as one net stereoisomer is formed!
