Which of the following order is correct for the decreasing reactivity to ring monobromination of the following compounds? A. ` I gt II gt III gt IV`B. `I gt III gt II gt IV`C. `II gt III gt IV gt I`D. `III gt I gt III gt IV` |

Answer» Correct Answer - B Bromination of arenes is an electrophilic substitution reaction. The higher the electron density on the benzene ring, more is the ease with which the ring undergoes substitution. The presence of +R effect increases the reactivity while -R effect decreases it `NO_(2)` is more deactivating than `-COOH` since N is +vely charged and withdraws more electrons form benzene than `-COOH` |
