The correct answer is: 2>1>3>4
+ R power depends on delocalisation of electrons in resonance, the more electron rich species can easily give their electrons for delocalisation. This also depends on electronegativity and charge on donar atoms. Negatively charged and less electronegative atoms are better donars.
