Answer Key : (d) -

  CH3 group when bonded to benzene increases the electron density of benzene by +I and hyper conjugation effects and hence makes the compound more reactive towards EAS.cl group decreases the electron density of benzene by –I effect, and cH3 Co group strongly decreases the electron density of benzene by –I and –R effects. Therefore, correct increasing order the given compounds towards EAS is
