In topscore, they say that F is a ortho-para activating director, but i just dont think that it is. any input on this?

All halogens including F are ortho-para deactivating directors as far as electrophilic aromatic substitutions are of concern.

TEST #1, Question #73

Doesn't 2-propanone (choice D) show only 2 singlets in the H1NMR Spec?

They have choice B.....
