for question 10, there would be 2 different form of product, and how to decide the optical activity?
and also, what determines optically active to inactive?
also, no idea how to deal with question 11
Homework Answers
Q1)) This reaction proceeds by SN1 mechanism. As the carbocation
intermediate is planar , can be attacked from either side of the
plane leading to both enantiomers in almost equal quantity. Thus we
get an almost equimolar mixture of enantiomers called racemic
mixture which does not show any optical activity[ due to external
compensation].![HO racemic mixture no (zero) optical rotation polas solvent solvent - Weak Nu SN[SOLYOLYSIS] the OTS de Sloco non backside l](http://img.homeworklib.com/questions/31fcd0e0-ddb7-11eb-9b23-018e196c3e79.png?x-oss-process=image/resize,w_560)
