5. An ethoxy group in aromatic substances in S_(E) reactions: is a meta director is an ortho/ para director speeds up S_(E) reaction is an electron acceptor

The correct answer is: is an ortho/ para director.<br /><br />In aromatic substances, an ethoxy group (-OCH2CH3) is considered an ortho/para director in $S_{E}$ reactions. This means that it directs incoming substituents to the ortho and para positions relative to itself on the aromatic ring.
