Question

Which of the following species is most stable

• A. P – O₂N – C₆H₄ – $\overset{+}{C}H_{2}$
• B. C₆H₅ – $\overset{+}{C}H_{2}$
• C. P – Cl – C₆H₄ – $\overset{+}{C}H_{2}$
• D. P – CH₃O – C₆H₄ – $\overset{+}{C}H_{2}$

Answer 1

Answer: (D)

P – CH₃O – C₆H₄ – $\overset{+}{C}H_{2}$

Answer 2

Positive charge on –$\overset{+}{C}H_{2}$ is dispersed due to electron repelling nature of methoxy group.
