Will nitrobenzene and benzene have the same rate towards sulphonation reaction, since the formation of sigma complex is not the RDS of this reaction?

Nitrobenzene and benzene would NOT have the same rate towards any type of electrophilic substitution reaction as strength of nucleophile - (nitro)benzene does matter.

Nitro group as in nitrobenzene is highly deactivating group due its electron withdrawing nature and therefore decreases the nucleophilicity of benzene ring.

  • $\begingroup$ But how shall it matter in "SULPHONATION" if the attack of electrophile, and thus the formation of sigma complex, is NOT the rds of sulphonation? $\endgroup$ – Anonymous Apr 14 '19 at 15:23

  • $\begingroup$ I don't think it should be used for emphasis, also using emphasising in multiple ways at once tends to be too much. $\endgroup$ – Mithoron Apr 14 '19 at 18:33
