Which of the following carbocations is expected to be the most stable?
Correct answer
0
Step-by-step solution
NO 2 is present at the ortho- and the para- position of a positive charge. NO 2 present at the meta-position of a positive charge is less stable due to the e - withdrawing effect of - NO 2 ( - I effect of NO 2 ) NO 2 present at the ortho- and para- of positive charge (Less stable due to the e - withdrawing effect of - NO 2 ( - M effect.) The positive charge is destabilized by the electron-withdrawing groups. - M dominates - I effect. So, the carbocation which has - I group is more stable.
