Question

consider the resonance structures of acetanilide and methylbenzoate provided above...

Several resonance structures of acetanilide are shown below: gh Resonance structures involving the amide group Resonance structures involving the aromatic n-electrons

Answer 1

a partial tal charges on methyl benzoate. chay on them - Cooch, group on methyl benzoate direct the incoming, electrophile to meta position, because we can see a ortho and para position there exist positive charge 8o electrophile being a positively charged species canno attach itself here. b) Partial charge on acetanilide 62-1 Partial charge on acetanilide direct the incorning electrophile towards ortho and para position because ortho & para position chave slightly negative change, which makes electrophilic substitution Pretty easier Partial change on methyl benzoate deactivates the incoming electrophile to ortho and para position because those Position contain positive charge so electrophile being positively charged cannot attach itself hore. c) Directing group activates the position where negative change is developed and deeactivate a position where positive charge is developed is case of Electrophilic aromatic substitution.
