CHXI12:ORGANIC CHEMISTRY SOME BASIC PRINCIPLES AND TECHNIQUES

317206 How many atoms or group of atoms given below will exhibit $+ I$ effect?
$Zn, CO O^{-}, R - S^{-}, I, Be, - S O_{3} H, - C (Et)_{3},$
$- COOH$

Explanation:

$Zn,CO O^{-}, R - S^{-}, Be, - C {(Et)}_{3}$ are electron donating groups and exhibit $+ I$ effect. On the other hand $I, - {SO}_{3} H$ and $- C O O H$ are electron withdrawing groups and exhibit $- I$ effect.
