NH2 is electron acceptor or electron donor?

    i have attached 2 photos here...

    the book said the NH2 exhibit negative inductive effect (negative inductive effect means electron acceptor) , and is ring activating group, but ring activating group is electron donor. which is correct?

    So NH2 is electron donor or electron acceptor?

    They were supposed to imply "generally".

    Both! While NH2 is a negative inductor, there is a resonance structure between NH2 and benzene that makes it a ring activator (the resonance dominates over the electronegativity).

    You can find a nice picture of the resonance here: http://www.chm.wright.edu/feld/chm212/eas.pdf
