Here the question is draw the products of each sn1 reaction, sn1 reactions are given and indicate stereochemistry of it if necessary.
00:16
So both the reactions which are given here, a and b, are sn1 reaction.
00:23
And in case of sn1 reaction, we know that it is taking place in two steps.
00:30
First step is formation of carbocatin and second step is attack of nucleophilic agent so here both are sn1 reaction first step formation of carboketine removal of br minus and formation of carbureticine so br is left here and carboketine formed must be this one, trigonar planar structure.
01:15
The thyl group will be here and the positive charge will appear here.
01:20
So this is trigonar planar structure of the carbuketan and now attack of nucleophilic reagent which is taking place from both the side because chances are equal.
01:36
So attack can take place from above the plane or it can be taken place from above the plane or it can from below the bill and by that the product which are formed is two products expected if it is attacking from up upper side then it should be and methyl group will go below the plane this part should be above and with the removal of one product second product is one part above the plane and this should be metal and the part which is below the plane should be och2 ch3 so this you can draw like this and both are isomers and they are mirror images of each other and chances are equal that is why you are getting recidemic mixture they are actually in in in shape us.
03:43
So this is the studio chemistry part of the product.
03:50
Now come to b...
