Current Question (ID: 10911)

Question:

$\text{The correct order of -I effect is:}$

Options:

1. $-\text{NR}_3^+ > -\text{OR} > -\text{F}$
2. $-\text{F} > -\text{NR}_3^+ > -\text{OR}$
3. $-\text{NR}_3^+ > -\text{F} > -\text{OR}$ (Correct)
4. $-\text{OR} > -\text{NR}_3^+ > -\text{F}$

Solution:

$\text{Hint: Electronegative element shows -I effect.}$ $\text{As the electronegativity of atom or group increases -I effect is also increases. Here, the order of atom according to their electronegativity is as follows:}$ $\text{F} > \text{O} > \text{N}$ $\text{But nitrogen containing positive charge is more electronegative than neutral nitrogen, Thus the correct order of electronegativity is as follows:}$ $-\text{NR}_3^+ > \text{F} > \text{OR}$ $\text{Thus correct order of -I effect is } -\text{NR}_3^+ > \text{F} > \text{OR}$
