Question

electron withdrawing group or meta directors is beacause of a) carboinum intermediate hase negative ion on meta group
b) carboium intermediate has postive charge on meta group ​

Answer 1

Explanation:

because of their ability to donate a lone pair of electrons in resonance forms, they are activators and ortho/para directing. Resonance forms win out in directing. Because they are electron withdrawing, halogens are very weak activators. Electron withdrawing groups are meta directors and they are deactivators.
