Why is hydroxide group an electron-donating group?
« on: October 20, 2009, 09:22:24 PM »
Generally, hydroxide group is known as electron-donating group when directly attached to benzene ring.

Actually, oxygen of hydroxide is heavily electronegative, and likes electrons.

then, Why is hydroxide group an electron-donating group?

I think that hydroxide is more like electron-withdrawing group when directly bound to aromatic nucleus.

What do you think?

Thank you for your reading!!

Look at resonance. Does the hydroxyl group have any spare electrons that it can donate to the benzene ring?
