Aldehydes and Ketones reacts with NH_2OH to form Aldoximes and Ketoximes respectively.Configuration of these can be determined by Beckmann rearrangement as that group migrates which is anti w.r.t-OH It is interesting to note that the migration of group is completely retentive and no loss of optical activity is seen. Following is true about product

Answer» It is also (+) laevorotatory Both (+) and (-) forms are obtained in equal amount It is having 'S' configuration for CHIRAL carbon it is having R configuration for chiral carbon Solution :SHIFT is retentive therefore INITIAL configuration will be maintained. Initially It is "S" and afterwards it will be "R" due to change in PRIORITY of atoms.
