Which of the following comparisons of Inductive effect power is correct according to the standard se — GOC and Organic Chemistry Basics Chemistry Question

💡 Solution & Explanation

As a rule exception in the inductive series, $-NR_3^+$ is a stronger $-I$ group than $-NH_3^+$. Fluorine is more electronegative than Chlorine ($-F > -Cl$). The $-CN$ group has a stronger $-I$ effect than an alkene. The alkoxide anion $-O^-$ is a vastly stronger $+I$ donor than a neutral methyl group.
