The groups which direct the incoming group to meta-position are called meta-directing groups. Some examples of meta -directing groups are - NO 2, - CN ,- CHO ,- COR ,- COOH ,- COOR, - SO 3 H etc.

Q. Which of the following set of functional groups is meta-directing?

$- N O_{2}, - N H_{2}, - COO H, - COOR$

$- N O_{2}, - C H O, - S O_{3} H, - COR$

$- CN, - C H O, - N H COC H_{3}, - COOR$

$- CN, - N H_{2}, - N H R, - OC H_{3}$

The groups which direct the incoming group to meta-position are called meta-directing groups.
Some examples of meta -directing groups are $- N O_{2}$ , $- CN, - C H O, - COR, - COO H, - COOR$ , $- S O_{3} H$ etc.
