Which of the following is correct with respect to −I- I effect of the substituent? (R=R =alkyl group)

Options

  1. A−NH2>−OR>−F- {NH}_{2} > - OR > - F
  2. B−NR2<−OR<−F- {NR}_{2} < - OR < - F
  3. C−OR<−NH2<−F- OR < - {NH}_{2} < - F
  4. D−NR2>−OR>−F- {NR}_{2} > - OR > - F

Correct answer

B. −NR2<−OR<−F- {NR}_{2} < - OR < - F

Step-by-step solution

{∴−NR2<−OR<−F:−Ieffect\begin{cases}∴ & - {NR}_{2} < - OR < - F: & - Ieffect\end{cases}

More the electronegativity of an atom, more is the −I- I effect.
