JEE Main 2 April 2026, Shift 2, Chemistry Q63

Question 63 of 75 in this shift, Chemistry question 13 of 25, Section A.

Given below are two statements: Statement I: In O_2N-\begin{array}[t]{c}\oplus \\ | \\ CH \end{array}-\begin{array}[t]{c} \\ | \\ \end{array}-OCH_3, the carbocation is stabilised by +R+R effect of −OCH3-OCH_3 group. Statement II: In O_2N-\begin{array}[t]{c}\ominus \\ | \\ CH \end{array}-\begin{array}[t]{c} \\ | \\ \end{array}-OCH_3, the carbanion is stabilised by −R-R effect of −NO2-NO_2 group. In the light of the above statements, choose the correct answer from the options given below:
