    bhai bhai bhai yaar ncert mai aqeous word use kiya hai,,,, dhyan se padh yaar exam mai aq word use nahi kiya hai,, and u are saniyg ki stability check karte hai then mai stability hi ka reson toi likh ke aaya hu,, 1 degree carbocation is most stable in sn2,, i think u are strugggling with your concept and meritnation ne jo likha hai vo sahi,, aapki tassali ke liye topper learning par bhi chale ja,,, but answer is sn2, i think teacher se tujhe apne puchna chahhye
