Question

When - $N^{+}$ ${(CH}_3{)}_3$ group is attached to the benzene ring. It orients the incoming electrophile into

• A. Meta position
• B. Ortho position
• C. Para position
• D. Equally directs group to ortho-para position

Answer 1

The correct option is A Meta position

As $\stackrel{\oplus }{-N{R}_3}$ in electron with drawing group and ortho-para directing so it decreasing the electron dimity at ortho-para position and at benzene ring.

That's why elecetrophile attack on Meta position of benzene ring.
