Question 75 of 90 in this shift, Chemistry question 15 of 30, Section A.

Given below are two statements : Statement (I) : SN2\mathrm{S_N2} reactions are 'stereospecific', indicating that they result in the formation of only one stereo-isomer as the product. Statement (II) : SN1\mathrm{S_N1} reactions generally result in formation of product as racemic mixtures. In the light of the above statements, choose the correct answer from the options given below :
  1. (1)Both Statement I and Statement II are trueOfficial answer
