WebThe -I effect of chlorine withdraws electron from Benzene ring. Hence tends to destabilize the intermediate carbocation formed during Electrophilic substitution. WebTo improve the QSAR correlations, substituents are usually divided into electron-donating groups (EDG) and electron-withdrawing groups (EWG), which are treated separately and thought to follow different mechanisms of toxicity. In this paper, we focus on one important aspect of toxicity, the rate constant for production of phenoxyl radical. ... kern county fog delays
