Question

Is Oh electron withdrawing or donating?

Answer 1

Answer:

OH is an electron donating group. In general, electron donating groups are ortho/para directors for electrophilic aromatic substitutions, while electron withdrawing groups are usually meta directors, with the exception of halogens, which are also ortho/para directors, as they have lone electron pairs shared with the aromatic ring.

Electron withdrawing groups have an atom directly attached to a benzene ring with a slight positive or full positive charge. Examples of groups that withdraw electrons: -CF3, -COOH, -CN. Withdrawing groups of electrons have only one major product, adding the second substituent in the meta position.
