Which of the following statements is correct? rhis question has multiple correct
Which of the following statements is correct? rhis question has multiple correct options
- A. Dipole moment
- B. Stability of free radical
- C. Basic strength: \( C H_{3} O^{\ominus}>\stackrel{\delta}{O} H>R \) S
- D. Basic and nucleophilic strength: \( I^{\ominus}>B r^{\ominus}>C l^{\ominus} \) > \( F^{c} \)
Step-by-step solution
Alkyl groups are electron-donating, increasing electron density on oxygen, making alkoxides stronger bases than hydroxide. Additionally, oxygen bases are stronger than sulfur bases due to better orbital overlap and higher electronegativity. Thus, the order CH3O- > OH- > RS- is correct.
