Among the following, how many groups have a stronger effect than the (Fluoro) group according to the — GOC and Organic Chemistry Basics Chemistry Question
Question
Among the following, how many groups have a stronger $-I$ effect than the $-F$ (Fluoro) group according to the standard Inductive effect series? $-NO_2, -CN, -COOH, -Cl, -Br, -OH, -NH_2, -NR_3^+, -NH_3^+$
Answer: 5
💡 Solution & Explanation
According to the standard $-I$ power series: $-NR_3^+ > -NH_3^+ > -NO_2 > -CN > -COOH > -F > -Cl > -Br > -I > -OH > -NH_2$. Therefore, the 5 groups stronger than $-F$ are $-NR_3^+$, $-NH_3^+$, $-NO_2$, $-CN$, and $-COOH$.
